How to Prepare a Toddler for a New Baby (Before and After)

A new baby is one of the biggest changes a toddler can go through. Their home, their routine and their place in the family all shift at once, and they are too young to understand most of it in advance. You cannot make it painless, but you can make it less of a surprise.

This is general information, not professional advice. Every family is different, and your pediatrician is a good person to talk to if you are worried about how your child is coping.

Tell them in a way they can understand

Toddlers have very little sense of time, so months are hard to imagine. Many families wait until the bump is visible, or link the baby to something the child understands: “The baby will come when it’s cold outside,” or “after your birthday.” Keep it simple and concrete: the baby will be very small, will cry a lot, will sleep a lot, and will not be able to play yet.

Make big changes early

If your toddler is moving rooms, moving from a crib to a bed, starting daycare or giving up the pacifier, many families do it a couple of months before the baby arrives, or wait until well after. That way the change does not feel like something the baby took. Our story about moving to a big kid bed can help with that one.

Practice with a doll

Toddlers learn through play. A baby doll they can feed, change, burp and rock gives them a way to practice gentle hands and to imagine what life with a baby will be like. It also gives them something to do while you are feeding the real baby.

Read about it together

Stories let a toddler meet the idea of a new baby many times before it happens, at their own pace. Read books about new siblings in the weeks before the birth, and keep reading them after. Our free social story about a new sibling is written for exactly this.

In the first weeks

Expect some regression. Toddlers who were using the potty may have accidents, children who slept well may wake more, and some want to be carried or fed like a baby. This is very common and usually passes. Small things help a lot: a few minutes a day of one to one time with each parent, letting them help with small jobs like fetching a diaper, and telling visitors to say hello to the big sibling first.

A free story to read together: Big Sister Lily

Lily’s mommy had a big round tummy, and inside it was a baby. “When will it come out?” asked Lily, every day. “When the leaves fall off the trees,” said Mommy.

Lily watched the trees. The leaves turned orange, then brown, and then, one windy week, they fell. And Grandma came to stay, and Mommy and Daddy went to the hospital, and when they came home, they had a tiny baby named Max.

Max was very small. He had a red face and tiny fingers, and he cried a lot, and he could not play anything at all. “He can’t even catch a ball,” said Lily. “Not yet,” said Daddy. “But he can hold your finger.” Lily held out her finger, and Max held on, very tight.

Lily had a job now. She fetched the diapers. She sang Max the song about the boat. And every night, while Max was asleep, Mommy and Lily had their own time, just the two of them, with a story in Lily’s big bed.

“I’m the big sister,” said Lily, as her eyes began to close. “Yes,” said Mommy, “the very best one.” And Lily fell asleep smiling, while down the hall, little Max slept too.
