Helping your child prepare for a new sibling: ABA strategies for big family changes

A new baby changes routines, attention, noise levels, and expectations. Even kids who seem excited can struggle when the change becomes real. ABA can help families prepare by teaching coping and communication skills, practicing new routines, and reinforcing flexible behavior.

What makes a new sibling hard for some kids

• Routine disruption: bedtime, mornings, and caregiver availability shift.
• Attention changes: caregivers may be less available in the moment.
• Sensory impact: crying, visitors, and new household sounds.
• Unclear expectations: “How do I act around the baby?”

Prep before the baby arrives

• Practice the new routine: “quiet time,” diaper changes, feeding times, shorter adult availability.
• Use visuals: a simple story or schedule about what will change.
• Teach a help/break request: “Help please,” “Break,” “My turn.”
• Reinforce gentle hands: practice with dolls/stuffed animals in calm moments.

Skills to target with ABA

• Waiting: tolerating short delays for caregiver attention.
• Flexibility: accepting small changes with support.
• Independent play: engaging in activities while caregivers are busy.
• Safe behavior: body boundaries and gentle interactions.

What progress can look like

Progress may mean fewer aggressive moments, better recovery when attention shifts, or more independence during baby routines.
