How to prepare a toddler for a new baby: a timeline

To prepare a toddler for a new baby, spread it out: tell them in concrete terms once the pregnancy is visible, make big routine changes well before the due date or well after, explain exactly who will look after them during the birth, and then protect some one-on-one time in the first weeks home. Expect a little jealousy and some backsliding. The American Academy of Pediatrics calls regression like potty accidents normal and suggests giving attention rather than telling them to act their age.

I have a 3-year-old and a 1-year-old, so this one is not theoretical in our house. What follows is a timeline built from the pediatric and early childhood sources linked on this page. If you are looking for picture books, those have their own guide: new baby books for siblings.

During the pregnancy: make it concrete

A toddler lives in the present. "The baby comes in March" means nothing at two. KidsHealth notes that preschoolers may not grasp time, and suggests linking the arrival to a season, such as "when it's cold outside." The same page says to let your child's questions guide how much detail you give.

Things that work at this stage:

• Point out real babies. ZERO TO THREE suggests noticing babies when you are out and visiting friends with newborns, then talking about what babies can and cannot do.
• Look at their own baby photos. "This was you. You were tiny and you cried a lot too."
• Give them a doll to care for. The AAP suggests a doll so they can look after "their" baby and get a feel for what it is like.
• Be honest that babies are boring at first. The baby will cry, sleep and need a lot of your time, and it will be a while before they can play together.
• Go easy on ultrasound pictures and appointments. ZERO TO THREE points out that a sonogram is very hard for a toddler to make sense of. Some toddlers like coming along to a checkup, some get antsy. You know yours.
• Ask about a sibling class. Many hospitals run them; KidsHealth describes classes that cover holding a baby and talking about feelings.

The last month: finish the big changes and make a plan

This is where a little planning saves a lot of tears.

Move rooms or beds early. KidsHealth suggests making any room shifts a few weeks before the due date, so your toddler does not feel bumped out of the crib by the baby.

Do not stack milestones. The AAP recommends finishing toilet training or the move to a big bed before the baby comes, or waiting until the baby is settled at home. If potty training is half done, it is fine to pause. Our potty training books guide has gentler ways to restart later.

Name the person who will stay with them. Leaving for the hospital is the moment that surprises toddlers most. Tell them, more than once, who will pick them up, where they will sleep and that you will come back with the baby. Practice a night at grandma's if that is the plan.

Let them help get ready, if they want to. Folding tiny socks, picking a toy for the baby. ZERO TO THREE warns against forcing it, because that tells a child they have to be happy about the baby.

Birth and the hospital stay

Keep the days around the birth as ordinary as possible for your toddler: same breakfast, same daycare, same bedtime song if the caregiver can manage it.

If you can, have them visit soon after the birth. KidsHealth suggests a visit when no other visitors are around, so the meeting feels like a family moment rather than a crowd. Some families have the baby "bring" a small present for the older child. It is optional, but it gives a toddler something to hold during a strange visit.

The first weeks home

Week	What helps most
First days	Greet your toddler before the baby when you walk in. Ask visitors to talk to them first.
Week 1 to 2	Keep daycare or preschool going if you can. A short daily one-on-one, even ten minutes.
Week 2 to 6	Invite small jobs, never require them. Hold the usual limits, kindly.
Any time	Expect regression and mixed feelings, and name the feelings out loud.

A few details from the sources that are easy to miss:

• Keep their routine. KidsHealth recommends continuing childcare or school if you are able, even though it can feel wrong to send them while you are home with the baby.
• Photograph them too. ZERO TO THREE suggests snapping pictures of the older child whenever you are photographing the baby.
• Teach gentle touch with a doll first. Same source: if they get rough, calmly take their hands and show them how, rather than snapping at them.
• Do not pressure them to love the baby. Babies do not do much yet, and ZERO TO THREE notes that pressure to feel warmly can make a child less likely to.
• Hold the line on limits. It is tempting to make up for the upheaval with extra treats and fewer rules. The same article says over-indulging tends to backfire.
• Feeding time can be together time. The AAP suggests having your older child cuddle next to you while you feed the baby.

Jealousy and regression: what is normal

Mixed feelings are the norm, not a warning sign. A toddler can adore the baby at breakfast and ask when it is going back by lunch. ZERO TO THREE lists asking for a bottle, baby talk and potty accidents as common signs of stress after a sibling arrives, and notes that demanding they act "like a big kid" often backfires.

What to say instead is simple: name the feeling ("You wish I could play right now. The baby needs milk first. Then it's your turn."), then follow through on the turn. If your child shows no interest in the baby at all, KidsHealth says not to be alarmed and not to force it. It can take time.

A small story of their own

Toddlers rehearse big changes through stories, and the best story is one with them in it. A few printed photos stapled into a booklet works well: our family now, the baby growing, who stays with you at the hospital, coming home, babies cry a lot, things we still do together. The new baby books guide walks through a seven-page version.

If you would rather not make it yourself, a personalized storybook is one option among several. Colorkin makes coloring storybooks from family photos, drafted with AI illustration tools and checked and finished by a person, where your toddler is the big sibling. A stapled photo booklet does the same job for the cost of printer ink.
