How do I prepare my toddler for a new baby?

What to expect from your toddler

A new sibling is a huge change for a toddler. Her person, the one whose calm she borrows when things go wrong, is suddenly busy, tired and holding someone else. Expect some backsliding: clinging, baby talk, toilet accidents. It's normal and it passes.

A toddler's brain is still building the wiring for waiting and stopping, so big feelings come out as big behavior. Jealousy at 2 can look like hitting, a meltdown over the wrong cup, or a sudden need to be carried everywhere. None of it means she doesn't love the baby. It means she needs extra closeness at the very moment you have less to give, so a few small, predictable habits matter more than grand gestures.

One worry to set aside: comforting her won't make it worse. Attachment research finds that children whose caregivers reliably respond are the ones who explore most confidently. Comfort refuels the tank, and a child with a full tank goes off to play.

Step by step

1. Start talking months aheadTell your toddler about the baby in simple words and read picture books about new siblings together.
2. Make her the story keeperIf you read a story to your bump, let her remind you, turn the pages and say the last word of each line.
3. Lock in routinesKeep bedtime the same and make a photo routine chart, so anyone helping can follow it after the birth.
4. Start special timeGive 10 minutes a day, phone away, child leads. Call it special time so she can count on it.
5. Name feelings and invite helpingSay the jealous feeling out loud, invite small jobs without forcing them, and notice her kindness to the baby.

Months before the birth

• Talk about the baby months ahead. Use simple, true words: "The baby is growing in my tummy. When it's cold outside, the baby will come." Read picture books about new siblings together.
• Give her a job now. If you read the same story aloud to your bump each day, your toddler can be the "story keeper": she reminds you it's story time, turns the pages and shouts the last word of each line. For a child unsure about this new baby, it's a way to feel like a helper instead of a bystander. After birth, she can "read" that story to the baby. Our page on reading to your baby in the womb explains the study behind the habit.
• Lock in routines. Toddlers fight less about what happens the same way every day: bath, pajamas, two books, song, lights. Make a photo chart of her bedtime routine and stick it on the wall at her eye level, so it still runs if Grandma or your partner does bedtime.
• Practice special time (below) before the baby comes, so it's already a habit she trusts.

Special time: 10 minutes she can count on

Give daily "special time" and call it by name so she can count on it. Ten minutes a day, phone in another room, and she leads the play. You follow, describe what she's doing and enjoy her. That's it.

Special time works because it's predictable. When the baby needs you right now, you have a true promise to make: "After I feed her, it's your special time." Then keep the promise, every day you can. On the days you can't, say so and name a new time.

Feeds are often the hardest moment, because your arms are full and her need spikes. Try reading to her while you feed the baby. Keep a basket of her books, or a few toys she only gets during feeds, beside your feeding chair.

What to say when jealousy shows up

Name the hard feelings instead of arguing with them. All feelings are allowed. Not all behavior is.

Toddlers have very few feeling words, so lend her yours: jealous, sad, mad, left out. The more often she hears them, the sooner she can reach for them instead of a shove. If meltdowns do spike, our page on handling toddler tantrums has the step-by-step.

Grow a helper, without forcing it

Toddlers are born helpers. At the Max Planck Institute in Germany, 18-month-olds watched a researcher "accidentally" drop a clothes peg and reach for it. Nearly every child helped at least once, with no thanks or reward. In a Canadian study, toddlers under 2 looked happier giving a treat than getting one.

So invite, don't force: "Can you pick the baby's socks?" "Can you bring me a diaper?" If she says no, that's fine. Ask again tomorrow. Thank her the way you'd thank anyone, and skip the sticker chart; our page on teaching toddlers kindness explains why rewards can backfire.

One safety note for little helpers who like giving presents. The baby sleeps on her back, on her own firm, flat surface, with nothing soft in the crib: no blankets, pillows, bumpers or soft toys. So your toddler's gifts for the baby go on a shelf, not in the crib.

Normal backsliding vs. a reason to call

Clinging, baby talk and toilet accidents in the weeks around a birth are expected. Keep routines steady, stay calm about accidents and give extra closeness. It passes.

Loss of skills is different. If your toddler stops saying words she used to say, stops making eye contact, or stops walking or using her hands the way she did, call your doctor now. Don't put that down to jealousy. There's often an explanation, and you want a professional looking for it soon.

And look after yourself. A newborn plus a toddler is a lot. If low mood, worry or a flat, joyless feeling hangs on most days, call your doctor or midwife. That's part of your children's health too.
