Helping Kids Adjust to Life With the New Baby

I’d just landed at LAX and was waiting at the baggage claim carousel when I heard an angry exchange. I turned toward the adjacent carousel and saw a three or four-year-old girl decked out in a colorful traveling ensemble – brightly patterned leggings, a trendy t-shirt and pink plastic movie star sunglasses. She seemed to be fumbling for something in her polka dot backpack while her father glared at her and seethed, “Just be nice. Be nice to your sister!”

Several feet away stood her mother, who also glared as she held baby sister (about 12 months old) in her arms. The girl kept her composure but avoided her parents’ gaze. She seemed alone and vulnerable — a “problem child” estranged from her family.

If this mini-snapshot was typical of her family dynamic, it was hard to fathom this little girl not feeling resentment towards her baby sister.

The arrival of a new baby is often the most dramatic change in a young child’s life, and if this transition isn’t handled with sensitivity and empathy, some children will have difficulty regaining their footing. At stake are our child’s healthy relationships with parents and siblings, as well as her sense of security and self-worth.

Here are some key points to keep in mind during this challenging adjustment:

1. Have reasonable expectations

A new baby causes a major shift in the family dynamics. No matter how much the older child may have wished for a baby brother or sister, the reality of this shift in the parents’ attention and affection is felt as a loss. Children often feel grief, sadness and sometimes anger or guilt, but mostly they are fearful of losing their parents’ love. Overwhelmed by this tumultuous blend of emotions, which are nearly impossible for children to understand (much less articulate), they act out their pain through irritating behaviors that are sometimes aggressive. Mood swings can be extreme.

Parents might be shocked to discover an unpleasant side to their child they hadn’t known existed, especially if they expected her to be a loving, adoring and helpful big sister during this adjustment. These behaviors are bound to push parents’ buttons, yet since the child is experiencing an emotional crisis she needs the assurance of her parents’ love and empathy more than ever.

2. Encourage children to express feelings

There are a couple of important ways parents can help children express their feelings in a healthy manner:

a. When children act-out with the baby — kissing or patting the baby too hard or jumping on the bed next to her — after calmly but confidently stating the boundary (“I can’t let you…”), the parent can ask matter-of-factly, “Are you feeling rough toward the baby right now? Are you upset that the baby’s here? Big sisters often feel that way. But I’m going to help you get down from the bed. I’d love for you to sit on my lap or jump on the floor next to me.”

b. Casually bring up the subject of negative feelings as often as possible: “Being a big sister is very hard sometimes. It’s normal to get angry at the baby or at mom or dad, feel sad, worry or just be upset and not know why. If you feel any of those things I want to know. I will always understand, love you and want to help you.”

It may feel counterintuitive to suggest these feelings to your child (won’t this encourage her to feel negatively toward the baby?). The truth is that the more you can openly accept and acknowledge, even welcome your child’s negative thoughts and emotions, the more space you will clear for your children to form a genuinely loving bond with their siblings.

3. But why mention negatives when my child seems fine?

Some children do seem to adapt to life with the new baby peacefully. Why would we project about problems that don’t exist?  It is my view that the children who seem more accepting and tolerant of this huge life change need even more encouragement to express negative feelings than those who overtly struggle. No matter how positive any change is there are also elements of fear and loss. For all of us.  If these feelings aren’t addressed and expressed, they are internalized. You may have a well-behaved child, but chances are good she’s suffering inside.

4. Avoid guilt-inducing comments  

When parents are expecting baby number two, friends and relatives will often comment to the firstborn child, “Oooh, bet you can’t wait to be a big sister!” But by then it’s already begun to dawn on the older child that ‘big sister’ isn’t all it’s cracked up to be.  They’ve sensed that the focus of everyone’s attention has shifted away from them. Their future feels uncertain and it will only get worse. They need someone who understands their pain and can assure them that their mixed feelings (especially the negative ones) are perfectly valid, or they are likely to turn these feelings inward.

5. Don’t judge

Again, this is about adjusting our expectations and understanding that button-pushing behaviors are the manifestation of our child’s pain and confusion. When we label a behavior “not nice”, “mean” or “bad”, children take these judgments personally. It’s not only the behavior that’s bad — they are bad. When the people they trust and need most in the world tell them they are “not nice”, they believe it, and the rejection they feel can be profound.

6. Lessen tension by not sweating the small stuff

Second children are born into a much different environment than their big brothers or sisters. Having an older sibling is exciting. So as much as possible, let it be. Let it be noisier and more chaotic, and let there be more interruptions to the baby’s playtime. Let big sister take toys away from the baby when they’re “playing together” as long as this is physically safe. Understand that this impulse is powerful and symbolic of the rivalry the older child feels. Most babies don’t mind the toys being removed from them unless their parents do.  In fact, this is the way they “play” with another child. The less you focus on these harmless behaviors, the less compelling it will be for the older child to repeat them.

7. Understand your child’s need for trust and autonomy 

Ask for her help whenever possible, especially regarding the baby’s care. When children’s emotions are out of control, opportunities to feel autonomous have a calming effect. But also don’t be disappointed if your child turns you down, because saying “no” is also a way for her to feel autonomous.

8. One-on-one time

Periods of time alone with your children are a necessity, but for both the baby and the older child it’s about quality, not quantity. Set aside at least 20 minutes a day in which you are wholly present and focused on your older child (which might mean aiming toward giving the baby an earlier bedtime). Then, when you need to focus on the baby and your child struggles, you can calmly acknowledge, “I see how uncomfortable it is for you when I am feeding the baby. That is really hard for you, I know. I’m so looking forward to our time together tonight after the baby goes to bed. Think about what you’d like to do together.”

9. Foster the baby’s independent play

A baby who can self-entertain is even more of a blessing the second time around, because his or her independent play creates opportunities for parents to be available to the older child without the baby always between them. Provide a safe, enclosed play space (a crib or playpen is fine for the first months), so that the baby doesn’t need constant supervision. Your toddler will probably need this boundary, because the impulse to test the parents by bothering the baby can be strong.

10. Respect your children’s continued need for boundaries and calm, helpful parents who are “on their side”.

Although extreme exhaustion or guilt might lead us to ease up on boundaries during this period of transition and emotional turmoil, our children need the love and security of our limits now more than ever. They’ll need us to give them matter-of-fact reminders like, “I don’t want you to touch the baby when you are in a jumpy mood”; choices like, “You can stay next to me quietly while I put the baby to bed, or play in the next room.” Sometimes they’ll need us to follow through by gently but firmly physically containing them or removing them from situations. Most crucially, they’ll need us to intervene way before we lose our temper or think they’re “not nice” and with all the confidence, calmness, patience and empathy we can muster.

  1. This is just what I needed to read as the mum of a little girl with a new cousin. The family gave all been wonderful but are starting to wonder why she isn’t more excited about the new baby. I am so thankful for the advice on how to help her through these new feelings.
    I will also be trying some of these suggestions with a child I work with. She has a baby brother, and although he is older I hope some of these approaches can help her and her family deal with how she is feeling.
    Thank you!

      I am 2 years older than my brother who was born in 1952.
      I did feel abandonment , and Mom saying with pointed finger ” be nice”. “Don’t be a bad boy.”.
      I picked him up and dropped him in his crib.
      It felt as the natural thing to do.I thought I would be praised. I was shocked at SHOCKING negative reaction from Mom especially and relatives calling me a ” very bad boy.”I might have gotten spanked. I was sent to bedroom, feeling massive shame and guilt. A foreign emotion which I have never felt before ; I did not know why.I did act out and internalized this treatment from Mom. ALWAYS in trouble with authorities :classmates , teachers and safety patrol–street crossing guards.

    What do we do when we feel like it’s too late? I wish I had read this article before the arrival of our son. My daughter is struggling and I feel like we have wronged her with our reactions and remarks. Her behavior seems to be totally out of control. How do I win her back? Please, help!

    1. I think you can still talk about it. Next time she acts out maybe ask if she needs a hug? Find time to talk about the feelings she might have been having & tell her it’s okay. Say sorry for specific reactions you’ve shown in the past that you realise were not right / came from being overwhelmed by your own emotions or expectations towards her. Hopefully she’ll see the change in your attitude. All the best!!!

  3. This is great for an older child who understands, but what about do you suggest for a child who doesnt quite understand such complicated ideas yet. My toddler will be 21 months when the new baby is born and I am a bit worried since he is too young for me to prepare him for a new baby brother. I am trying to teach him concepts like “being gentle” and “sharing” but I know that is not enough. What else can I do? Right now he is 16 months.
    I am also worried because he does not go to daycare and while I do take him to the park, he doesnt often interact with babies his age or younger. He is a very loving, enthusiastic and intelligent boy, loves to fake laugh to make us smile and randomly gives us hugs and kisses. At the same time, he also occasionally smacks, bites, and throws his head back when we are holding him. He is very used to being the only child at home and having my attention whenever he needs it.

    1. Katy Wood says:

      Our daughter was 18 months old when our youngest was born… Basically following what Janet says worked really well. Our 18 month old lashed out at her new sister – I’d make it boring and matter of fact “I’m going to put your sister where you can’t touch her while you calm down”. It didn’t last long, because the 18th month old quite liked having a baby on the floor to stare at… and while the baby napped I’d make sure to read a book one on one with her older sister.

      1. Really helpful, Katy, thank you for sharing your experience.

  4. Great information Janet, have you got any posts about preparing a child for a new baby? I’m due with my second in 3 months. My first will be just over 3yo. I have one big sister book I’ve been reading but feel we need to do more to prepare but not sure how to go about it. She’s very bubbly and boisterous and enthusiastic but used to being the centre of her universe. I’m not sure how to better prepare her.

    Hello, I am working with a family what are expecting a new sibling and the older sibling would benefit from this social story

  6. Hi Janet, love this article. I have one question, we have a 20 month old son and a few days old baby girl. Our son has a very gentle and caring nature, he is very lovely with the baby but anytime she cries for food or wind, he takes it so personally and starts crying too looking so genuinely sad and stressed he has hurt the baby even though he didn’t apart from the odd accidental poke when he is showing interest in baby sister.
    How do I help him to cope? He worries so much about her it makes me worried about him.
    We follow gentle parenting and talk about everything but he is still quite little himself (and from a bilingual family) so I feel like he doesn’t quiet understand everything yet.
    Thanks for any advice.

  7. How do we get grandparents on board with the program?
    My mom/the grandma comes over twice a week to help us out with the newbaby.
    While the approach seems to be working with us, the parents, and our eldest child,
    my mom/the grandma has been struggling and our child acts out more with her now. He disrupts her chores like pulling out clothes she is folding or jumping around the sofa she is cleaning.
    Because of repeated outbursts like this, I see also that she is starting to feel negatively towards him. I’ve heard her call him a brat and respond “I dont like you too” to my son. This breaks my heart.
    How do I share this parenting philosophy with my mom/the grandma without appearing to criticize the more authoritarian approach she used to raise me? I tried to talk about it with her, I asked if she could hold off from doing laundry when the child is with her etc. I encouraged her to instead just play/ spend quality time with him. But her response is that she feels triggered and that I should start “really disciplining” my son.
