Tantrums, regression and anxiety can be normal responses to losing a parent’s undivided attention. Experts share ways to help firstborn children adjust with confidence.
Firstborn children can react strongly when a new baby arrives, and that response is often less about misbehaviour than about uncertainty. For a child who has been the sole focus of parental attention, the arrival of a sibling can feel like a sudden loss of status. Utah State University Extension says that in the months after a baby is born, some children show tantrums, sleep disruption, regression or anxiety, all of which can be normal reactions to a major family change.
Experts say the best preparation starts before the birth. Cleveland Clinic and HealthyChildren.org both recommend talking about the baby early and in language the child can understand, while also using picture books, dolls or role-play to make the idea feel real. The message should be simple and reassuring: the family is growing, not shrinking, and there is still enough love to go round.
Keeping everyday life steady can also help. Utah State University Extension advises parents to preserve familiar routines, such as bedtime rituals, songs or mealtimes, because predictability can make children feel safer. The same guidance appears in advice from Franciscan Health and HealthyChildren.org, which stress that involving older children in small preparations, such as choosing clothes or helping get the nursery ready, can build a sense of inclusion rather than exclusion.
Specialists also encourage parents to carve out short stretches of one-to-one time with the older child. Even 10 to 15 minutes of reading or play can reassure them that they have not been replaced. The child should be invited to help with the baby in age-appropriate ways, but not burdened with responsibility. The point is connection, not pressure.
Perhaps most importantly, parents are urged to name the child’s feelings instead of dismissing them. Utah State University Extension says it is better to acknowledge jealousy, anger or sadness than to shame a child for expressing them. When caregivers respond with warmth, consistency and emotional attunement, the adjustment usually becomes easier over time, and many firstborns eventually grow into their new role with pride rather than resentment.
