When a new baby arrives, it can be a big adjustment for older siblings. Boston Children's psychologist Dr. Erica Lee offers simple strategies to help kids adapt, from preparing them in advance to involving them in caring for the baby and setting aside one-on-one time.

Why it matters

Welcoming a new sibling is a major life change for children, who may feel confused, overwhelmed, or even resentful at first. Helping kids adjust positively can strengthen family bonds and set the stage for a lifelong sibling relationship.

The details

Dr. Lee recommends starting the conversation about the new baby early, reading children's books about becoming a big sibling, and letting older kids help prepare by picking out clothes or decorating the nursery. She also suggests teaching them how to hold and care for a baby using dolls or stuffed animals. Once the baby arrives, it's important to validate older kids' feelings, set aside special one-on-one time, and even have them "help" the baby by waiting their turn or letting the older sibling's needs take priority.

  • The new baby is expected to arrive in the coming weeks.

“If they're old enough, you can talk to them about why is it so frustrating? Or why is the baby upsetting you? How can we cope with that?”
