Helping Your Child Adjust to a New Baby

Written by Leena Tabaja. Customer Service Coordinator & proud mom of two.

I bet you didn’t know that summer is actually peak birth season in Canada- and I’ll even bet that you or someone you know is expecting a baby right now. With summer right around the corner, many growing families are busy preparing to welcome a new little one into the home: setting up nurseries, stocking up on diapers and baby essentials, getting everything ready for life with a newborn. While this chapter can be filled with excitement and anticipation, it can also bring big emotions for older children as they adjust to changes in attention, routines, and family dynamics, and you may be wondering what that dynamic will be like. If you already have children at home, you’ve probably found yourself wondering how they’ll react to the new baby. Will they still be excited to have a new baby at home? Will they be confused, protective, emotional, or even a little jealous as they adjust to sharing their parents, space, and routines with a new sibling?

Sibling jealousy is incredibly common, especially in the early stages of adjusting to a new baby in the family. Even children who seem excited during pregnancy may struggle once the baby arrives. For many parents, this can feel unexpected or discouraging, but in most cases, these reactions are a normal part of adjustment, not a reflection of poor parenting, favouritism, or a lack of love between new siblings.

Why Sibling Jealousy Happens

For an older child, a new baby can suddenly shift the world they’ve always known. Parents who were once fully available are now feeding, soothing, and caring for a newborn around the clock. Daily routines may change, patience may feel thinner, and older siblings can sometimes feel unsure how to fit into this new dynamic.

Jealousy can present itself in different ways, depending on the child’s age and personality. Some children become clingier, more emotional, or more sensitive. Others may regress behaviourally and ask for bottles, diapers, or baby-like attention. Tantrums, frustration, or acting out are also common ways that children’s express feelings they don’t yet know how to communicate.

At its core, sibling jealousy is often less about the baby itself and more about seeking reassurance, connection, and security from their parents.

Preparing Older Siblings Before Baby Arrives

One of the most helpful things parents can do is begin preparing older children before the baby is born. Talking openly about what to expect can help make the transition feel less sudden and overwhelming.

Using simple, age-appropriate language, parents can explain that babies cry often, sleep a lot, and need extra care in the beginning. You may also mention that you may need their help with the new baby too, and that becoming a big brother or sister is an important and special role. For many children, feeling included and needed can help create excitement and connection before the baby even arrives.

Reading books about becoming a big brother or sister can also help future siblings feel included and emotionally prepared for the transition ahead. It’s also important to remind older siblings that while routines may change, parental love does not.

Be Mindful Not to Blame the Baby

In busy moments, it’s easy to say things like, “I can’t right now because the baby needs me,” or “Don’t wake the baby.” While completely understandable, repeatedly framing restrictions around the baby can unintentionally create resentment over time.

Instead, small wording shifts can help preserve connection. Saying things like, “I’ll help you in one minute,” or “We’re taking care of the baby together,” can make older siblings feel included rather than pushed aside. These subtle changes in language can have a meaningful impact on how the older sibling adjusts to and connects with the new baby during the transition period.

Prioritize One-on-One Connection

Creating small moments of uninterrupted one-on-one time can help older siblings feel secure and emotionally grounded. This doesn’t need to be elaborate or time-consuming. Reading together before bed, going for a short walk, baking, or even spending ten focused minutes playing can make a child feel valued and seen, offering them a sense of comfort and familiarity during a time of change.

Involve Them Without Too Much Pressure

Many children enjoy feeling included in caring for the new baby, especially when it feels fun and low-pressure. Letting older siblings help choose an outfit, bring a diaper, sing softly to the baby, or join in during bath time can be a beautiful way to spark curiosity, connection, and excitement.

The key is to keep these activities optional and playful, rather than something they are expected to do. This helps them stay connected to what’s happening in the family and feel part of the experience of being an older sibling, without it feeling like a burden or responsibility they must carry.

Make Space for Big Feelings

Welcoming a new baby is a major life change for the entire family. Older siblings may feel love, excitement, frustration, sadness, and jealousy all at once. Validating their feelings helps them feel safe expressing themselves. Acknowledging that it’s hard to share attention or that they miss having more one-on-one time can go a long way in helping them process what they’re feeling.

Children do not need perfect responses from parents. More than anything, they need to feel heard, reassured, and emotionally supported.

The Goal Isn’t Perfect Harmony

Sibling jealousy and rivalry are a normal part of family dynamics. The goal is not to eliminate every difficult moment or to create a perfect, peaceful household at all times. Instead, the focus should be on building security, trust, emotional connection, and healthy communication within the family.

If you’re currently navigating this transition, it’s important to remember that struggling moments don’t mean anything is going wrong. A growing family is a big adjustment for everyone; learning how to grow together takes time, but it often becomes one of the most rewarding parts of parenthood. Some of the most meaningful sibling bonds are built slowly, through the ordinary little moments shared over time.
