Best Friends: Encouraging Sibling Relationships 

Today we’re talking all about how to encourage sibling relationships, reduce those sister squabbles, and find more joy in family relationships. This post was originally published back in January 2018.

I’ve had a few questions and done A LOT of thinking about how to encourage sibling relationships over the last few months and get my kids to play together.

With two toddlers at home, I’m either breaking up an argument or melting over joint giggles coming from the other room.

Watching Lincoln and Adelaide turn into the best little friends is, hands DOWN, my favorite part of motherhood.

First smiles were great, first “mama” was enchanting, but watching these two love each other is ten times better.

I sought out SO much advice on the first stage of their relationship, introducing Lincoln to his new sister in the hospital and the transition to two children. I had a harder time getting advice and was initially less intentional on having them grow into being friends.

Also, I am not the expert. I have two kids and have been a mother for three short years. These are a collection of things I’ve learned, things I’ve read, and things I’ve heard… all through the lens of what we’ve been working on over the last few months about sibling relationships.

Siblings that get along are rewarding in the long run (my three siblings are some of my very best friends) but they’re also super practically beneficial right now. I often say that two is easier than one …. and most of the time these days it’s true. They entertain each other, they engage each other, and if I’m lucky, they do it happily.

Here are ways to encourage sibling relationships from an early age and get them to be friends with each other. For reference, at the time of this post, Lincoln just turned three and Adelaide is 19 months: 


1. Start with side-by-side play

Even when children aren’t playing together, encourage side-by-side play by setting up different play “stations” in the same room. I’m using the term “stations” loosely here – I put Lincoln with some cars at the kid’s table and Adelaide with some blocks on the floor. Usually after a few minutes of playing alone one will wander over to the other and they’ll begin playing together.

2. Time

Have you heard the saying “Love is spelled T.I.M.E?” I think it’s true in sibling relationships as well. Give siblings the chance to become playmates by having ample time for them to do things together.

3. Don’t Force it

Depending on the age gap and current ages, your children might not be ready to be playmates. Or maybe they are, but on any given day, one of them just isn’t feeling it. Be okay with them playing separately. Don’t force them to play together.

In the early months Adelaide loved to watch Lincoln play and now most days they play together. But, some afternoons Lincoln wants to play by himself and I find a space where he can play uninterrupted. He will usually want Adelaide to come join later, or come back to playing with us after he’s had his time, but this option to go play alone is important. Adelaide hasn’t showed a similar need (she’s an extrovert from what I can gather, though, and Lincoln is definitely an introvert).


4. Communal toys

One piece of advice I got was to have all the toys be shared, nothing belonging to a specific child. We don’t do this exactly, but for almost all the toys, they belong to the family.

Each child has their own blanket and security item. Other than that, we have never emphasized toys belonging to a certain child. When Adelaide got a cooking set at a gift exchange and Lincoln got a car set, we put them both on the shelf and invited both kids to play with both toys.

5. Talk about the importance of family + loving each other often

Make the discussion of family and the love you have for each other a frequent one.

I can see the sense of pride and belonging Lincoln feels when we talk about being a family. In addition to making him feel loved and included, it strengthens his understanding of his connection with Adelaide. Also, because Adelaide is just learning to talk, our verbalizing her feelings for the rest of us helps Lincoln understand that she loves him.

In practice: I’ll say things like “Lincoln, I am so glad you are part of our family. And I’m so glad I get to be your mom. I am so glad Adelaide is part of our family.” We’ll also ask things like “Who loves Lincoln?” and then help Lincoln list all the family members that love him. Other times I’ll mention that I love Daddy and Lincoln will chime in “and I love Daddy!” and we’ll continue it for the rest of our family members.

Additionally we try and create a family culture about being happy, helpful, and kind (probably another full blog post). I try to use statements like “In our family, we are helpful – thank you so much for putting away those cars – that was so helpful!”

6. Prioritize people over things

If they fight over it, take it away.

I HATED this rule as a kid and it is one we are just starting to implement. If our kids can’t get along with a certain toy, the toy gets put away and no one gets it. This encourages them to find a way to work it out, take turns, or play together.

7. Encourage communication

Giving kids a way to express their feelings and have them validated often solves the problem of a disagreement. When my kids are starting to get frustrated, or sad, or hurt, I label their feelings. Lincoln is old enough at three that he can repeat what I’m saying or express it on his own.

In practice:
I ask something like, “Lincoln, what is wrong?”

Lincoln usually responds with the action that bothered him, ” Adelaide took the car that I was playing with.”

I respond with labeling his emotion, “You’re feeling sad because you wanted to play with the car.” (I also try to keep this part focused on him so it’s “you’re sad because you wanted to play with the car” instead of “you’re sad because Adelaide took the car” but I’m not always consistent about this).

Lincoln will usually confirm with, “Yes, I’m feeling sad.”

Sometimes this recognition of his feeling is enough for him to move on from it.

8. Encourage Empathy

To continue the previous conversation, once we’ve established Lincoln is feeling sad and wanted to play with the car, I’ll turn to Adelaide and say, “Adelaide, look how sad Lincoln is because he wanted to play with the car! What could we do to make him feel better?”

Now, Adelaide, at 18 months, is still quite young. Most of them time I need to bring up the solution.

The point is, focus on helping your kids recognize the emotions of their siblings before trying to make things fair. If Adelaide takes a toy, I’ll often make her give it back. If Lincoln knocks over a tower and refuses to help build it, he’ll need to go play somewhere else. But, before those consequences, I try to help them recognize how their sibling is feeling as a result of their actions and give them the opportunity to fix it.

Most of the time at our house this plays out after Lincoln has taken a toy from Adelaide and she’s crying. After this conversation with Lincoln he’ll usually suggest giving her another toy. The judge in me wants to make him give back the original toy but I let him try this solution and if Adelaide is happy with it, I let it be.

9. Comfort before discipline

One rule of thumb a friend shared a few months ago was to always comfort the victim first. Instead of jumping in to discipline the child who took a toy, threw a block, or hit, make sure the child that got hurt or is sad gets your attention first. A lot of the time acting is out is a cry for attention and when you reward it with your immediate attention (even if it’s negative attention), that encourages the behavior.

In practice: When Lincoln has taken a toy from Adelaide, I’ll comfort her first. “Adelaide, you’re feeling sad because you were playing with that toy and now Lincoln has it.” before turning to Lincoln and helping him empathize, “Lincoln, Adelaide is feeling sad after you took that toy away, what could we do about it.”

I also try this when my kids do something to another child. Like last week at playgroup Lincoln threw a ball straight at the face of the one year old. He got removed from the situation and needed to come hang out with me for awhile (“because if we can play if we are going to play nicely”)  but only after he was ignored while I made sure the other child was okay (while being thoroughly embarrassed and super frustrated with my three year old who should know better).

10. Let them be crazy

The most laughter we have in our house is when Adelaide and Lincoln are running around together being a little bit insane. If I can, I just let them be.

As long as the kids are having fun and no one is getting hurt, let them keep at it.

11. Stay out of it

As long as you can, stay out of it, especially if they’re having a disagreement. Give them a chance to work it out before you get involved. You might be surprised at how they can resolve it.

It is more important for them to find a solution that works for them than for you to execute the solution you think is fair. We have a lot of things go on that aren’t fair between my kids but if they can find a solution on their own that works for both of them, I call it a win.

Of course, if the fighting doesn’t stop within a minute or so, I’ll often intervene (when they get older I think they’ll be able to disagree and work things out for a longer period of time – but, as toddlers, a minute of pulling on a toy is plenty long).

12. Compliment and highlight acts of kindness

Whenever you see your child serving, sharing, or helping the other, compliment or highlight it. In addition to calling out the action, label it as kind or helpful.

In practice: When Lincoln picks up a toy Adelaide dropped and gives it back to her I’ll try and say something like, “Adelaide, that was so kind of your brother to give your toy back. He is such a helpful big brother.”

This also acts to encourage helpfulness between siblings and I’ve found Lincoln is more apt to serve and help Adelaide since I’ve started recognizing his efforts.

13. Role play positive responses to conflict

Give your kids the communication tools early to express their feelings and deal with conflict in a healthy way. An easy way to do this is role playing responses you’d like them to use in situations.

In practice: When Adelaide has taken Lincoln’s toy and he is screaming I’ll try and say something like, “Lincoln, you’re feeling frustrated because you were playing with that toy. You can say ‘Adelaide, I was still playing with that. May I have it back please?'” We also like “It’s still my turn. Would you like a turn when I’m done?”

14. Set some basic rules

Help your kids understand the basic framework in which they play together. I’m still working on what our rules are in our family but the one I go back to often (usually daily) is “We don’t take things from hands.” This means that no matter what, even if you were playing with something and Adelaide picked it up from the road you were building and walked away, you can’t pull it out of her hands.

15. Show how fun it is

Show your kids how fun playing with their sibling is. Sometimes Lincoln won’t want to join in building blocks with Adelaide but if I sit on the floor and have a great time with her, laughing and playing, he’ll often join. I can keep playing for another minute or two and then they don’t notice as I slip away to clean the kitchen.

16. Encourage teamwork

Find things your kids can accomplish together to build a sense of comraodery and teamwork. One great way is to give them simple household tasks to do. With toddlers, we like to ask them to clean up a bin of toys together, encourage them along, and then celebrate their completing the task together.

In practice: I’ll ask, “Lincoln and Adelaide, can you two clean up these cars by putting them in the car bin?” I’ll encourage them with, “Great job – Adelaide and Lincoln are putting the cars away and that is so helpful!” When they’re done I’ll thank them, “Thank you guys for working together and cleaning up – that was so helpful.”

17. Don’t compare

In front of them, or where they could overhear you, don’t compare your kids.

This one is SO hard for me because I find their differences so interesting and sometimes surprising. But, I’m trying to keep the conversation with Ben saved for after they’ve gone to bed or are well out of earshot.

18. Give them enough one on one time and attention

We don’t get a lot of one on one time with each of our children but I find that when Adelaide is playing happily I can sneak in building a tower with Lincoln and giving him my undivided attention. Alternatively, when Lincoln is racing cars I can sneak in a story on the couch with Adelaide. Both my kids are better behaved and kinder to each other when they’re feeling loved and aren’t seeking additional attention.


A few other things about sibling relationships:

When we go to the gym and I drop my kids off I’ll often ask Lincoln to look after Adelaide and make sure she’s feeling “safe and loved” (a phrase we use a lot around here). When I ask him about if afterwards I can sense the pride and responsibility he feels for having a task and taking care of her. I’ll often get a response like “Adelaide cry but I gave her a ball.” or “Adelaide and I play together.”  I love finding ways I can encourage them to watch out for each other.

One piece of advice I got (or read) before Adelaide was born was to not blame the baby for not being able to help my toddler. If Lincoln wanted me to pick him up while I was feeding Adelaide, instead of saying, “I can’t hold you right now because I’m holding Adelaide,” I’d say, “My hands are full right now. I would love to pick you up in a few minutes.” I’m not sure if this actually made a difference but I like the idea of not calling out how the sibling is taking away from the other.

Also, buy them darling matching rain boots. These two love wearing these and always want the other to be matching. We got ours from London Littles and they couldn’t be cuter.

  1. This post was amazing. I’m currently pregnant with my first, but the idea of a large family is always running through my head. I also think these ideas work even with close friends and cousins.

    1. Awesome! Thanku for the extremely helpful teachings & suggestions… i am starting to implement slowly, these bonding and easy understanding techniques. Wow! Great! Thank you!

    2. This post is great! I have a 2.5 yr old and a 6 mo old and this is all VERY useful!

  2. This has been an amazing read, sounds like you’re doing a great job mama! My youngest is 2 months old, while his older brother just turned 2 years. My toddler just adores his baby brother & this is the type of encouragement I need to maintain that love between the two! Thank you for the great advice!

  3. Great post. It’s so true that siblings make the best friends. Building those relationships does take some time and effort, but it’s so worth it!

  4. Wow, this is awesome. Also…. I got a bit freaked out by similarities between our families. My two kiddos are Lennon and Adelaide. (We actually had Lincoln as our #2 choice behind Lennon!) and they actually kind of look like your kiddos too – Lennon is a little blondie and Adelaide has lots and lots of dark hair – crazy!

  5. Good article, i have two kids who are now 11 (girl) and 13 (boy)… The only thing i don’t agree with is the communial toys, i believe each child should have their own toys, but they are also taught to share them.
    I have been blessed with two awesome kids and yes the older boy is more introvert and the second child, the girl is extrovert… I find this to be quite common.

    1. Hi! Yes, I’m with you, as kids get older I think we’ll definitely do individual toys. Right now my kids are 1 and 3 and play with all the same things so it’s been a lot easier to make things communal but as they get older I can see the value (and practicality) of having their own things!

  6. This was a great read! Thank you for sharing!!!
    I have two girls (5,2) one thing that has helped us has buying two of most things and in different colors. If I get a doll for 5 year old, then I will get one for my 2 year old as well… it’s has alleviated a lot of arguments between them…

  7. I really really appreciate this post! I’m currently expecting our second little one and the kiddos will be exactly 2 years apart. It seems like everything I’ve read lately talks about how hard it will be to have two kids and all of the problems that we’ll face but this article just made me so excited to grow our family! I can’t wait to watch our kids become friends and will definitely be utilizing these tips! Thank you so much:)

  8. This is excellent- I’m glad Pinterest suggested your blog! I have 4 daughters, and I’ve noticed with my older two (8 and 6) that finding extra-cirriculars that they both enjoy has given them an awesome boost in their relationship. Currently, they’re each playing on their own soccer team, but they practice together at the park and at our house, and are learning to cheer each other on during their games. My oldest often teaches the younger one new skills that she’s learned. Keep it up Mommy, you’re doing a great job!

  10. I very much enjoyed this article. I implement many of these suggestions, which, despite getting on each other’s nerves as they got older, continue to work (mine are 7&9). Your children are adorable and their names are lovely. I am slightly biased, though; I have an Adelaide and a Luca.

  13. Well Narrated!
    We should never compare two children. This increases the jealously between them. Which as a family is not good. We should appreciate both equally. They should never feel that parents love one child more than the other one.

  14. Love and agree with all of this- spot on! A few specific activities I’ve seen that are super successful that we’ve tried for older siblings is a game board that they work together to complete for an agreed upon outing prize. The catch is it’s sibling kindness activities to do in order to cross off like “do a chore for your sister”

    Another is to give them each money, send them into a small coffee shop together while supervising from a distance and allow them to have a sibling date.
