How to Handle Sibling Jealousy When a New Baby Arrives

Gentle strategies to help your older child adjust to a new baby and reduce sibling rivalry.

1. Prepare Before Baby Arrives. Many families find it helpful to start preparing their older child weeks or months before the baby is born. Read books about becoming a big sibling together, and let them help set up the nursery by choosing a special toy for the baby or arranging stuffed animals. Some parents create a photo book showing what life was like when the older child was a baby, emphasizing how much they were loved. Consider timing when you share the news. Very young children might not understand the concept of months, so some families wait until closer to the due date. Let your child ask questions, and be honest about changes that are coming—like Mom being tired after the baby comes, or having less one-on-one time initially.
2. Validate Their Feelings. When jealousy shows up, resist the urge to dismiss it with phrases like "you're such a good big brother" or "the baby loves you so much." Instead, acknowledge what they're experiencing: "It's hard when Mama has to feed the baby and can't read to you right away" or "You're feeling upset that we can't go to the park because the baby is napping." Some children express jealousy directly ("I don't like the baby"), while others show it through behavior changes like tantrums, sleep disruption, or regression in potty training. Both are normal responses to a major family change.
3. Create Special Time. Even 10-15 minutes of focused, uninterrupted time with your older child can make a significant difference. Some families designate this as "big kid time" when the baby is napping or when your partner can watch the baby. Let your older child choose the activity—whether it's reading, playing with blocks, or just talking. Consider creating small rituals that belong just to them. Maybe it's a special snack you share while the baby naps, or a song you sing together during bath time. These moments help reassure your child that they still have a unique place in your heart.
4. Include Them Safely. Many older siblings want to help with baby care, and finding age-appropriate ways to include them can reduce feelings of being left out. Toddlers might bring you a diaper or help choose the baby's outfit. Preschoolers can sometimes hold the baby with lots of support, or be your "helper" during diaper changes by throwing away the old diaper. Always supervise closely and be ready to redirect if your child seems overwhelmed or rough. Some children prefer to help in non-direct ways—like being your "reporter" who tells Daddy what the baby did while he was at work.
5. Manage Your Own Stress. Sibling jealousy often peaks when parents are most exhausted and stretched thin. If you find yourself snapping at your older child for normal big feelings about the baby, that's a sign you might need more support. Tag-team with your partner when possible, accept help from family or friends, or consider having your older child spend time with grandparents or other caregivers. Remember that some regression is normal and temporary. A potty-trained three-year-old might have accidents, or a child who was sleeping through the night might start waking up. Most children work through these phases within a few months as the family finds its new rhythm.
