## TLDR

- Tell a toddler a few months out and tie the date to something they understand. Be honest that babies cry a lot and can't play yet.
- Make big changes (new bed, daycare, potty) a couple of months before the birth, or wait until a couple of months after.
- Plan who cares for the toddler during labor, ideally someone familiar, and start sharing bedtimes with the other caregiver now.

## When to tell them

Toddlers have little sense of time, so months of "the baby is coming" can feel endless. Many
parents tell a 1-3 year old once the bump is showing or a few months out, and tie the date to
something they understand: "when it's cold," "after your birthday."

## Make it concrete and honest

- Read picture books about new siblings and look at their own baby photos together: "This is when
  you were tiny and we fed you like this."
- Be honest about what babies are like: they cry a lot, sleep a lot, can't play yet, and need lots
  of feeding. A toddler who expects a playmate is often disappointed.
- Practice with a doll: gentle hands, quiet voices, how to hold while sitting, waiting while the
  doll "feeds".
- Visit friends with a baby, if you can, so it's not all theory.

## Make big changes early (or late)

Move to a big bed, a new room, starting daycare, potty training or weaning well before the due
date — a couple of months if you can — or wait until a couple of months after the baby is settled.
(AAP HealthyChildren: finish major changes before the baby arrives, or put them off until after.)
Otherwise it can feel like the baby pushed them out. If a change can't move, frame it around the toddler's growth, not the baby.

## Shift some routines now

If the birthing parent does every bedtime and bath, start sharing them with the partner or another
caregiver during pregnancy, so the toddler is used to it before birth recovery.

## Plan the birth days

- Decide who cares for the toddler during labor, ideally someone they know, at home or a familiar
  place, and do a practice sleepover if it's new.
- Tell them in simple steps what will happen: "When the baby is ready to come, Grandma will stay
  with you and we'll go to the hospital. Then we'll come home."
- Leave a photo of the parents, a short recorded story, or a small surprise per day.
- Video calls or a short hospital visit can help; for some toddlers saying goodbye again is harder,
  so keep visits brief.

## Give them their own role

Let them help pick a baby blanket or toy, choose a song to sing the baby, or make a card. Keep it an
invitation, not a job.

## Prepare yourself

Expect some regression and big feelings after the birth; it's normal and usually passes. Line up
help now (meals, school runs, a grandparent visit) so someone can give the toddler attention while
you recover.
