Before the baby arrives

How do you introduce a new baby to an autistic sibling? Begin with a “baby plan” your child can see.

• Keep daily routines as consistent as possible.
• Practice the hospital plan: who will stay with them, where they will sleep, and when they will see you.
• Use pictures and short stories to preview baby sounds, feeding, and safe hands. Social story style tools are commonly used in autism supports.
• Set up protected one on one time on a schedule, even 10 minutes daily, so attention does not suddenly drop.
  
  

The first meeting at home

How do you introduce a new baby to an autistic sibling? Make the first minutes calm and structured.

• Greet your child first with a hug, then introduce the baby.
• Keep the baby in an adult’s arms at first. Offer a simple job: bring a diaper, choose a blanket, or press the white noise button.
• Limit visitors and noise during the first introductions. A quieter environment lowers stress for many autistic kids who have sensory differences.
  
  

The first two weeks

How do you introduce a new baby to an autistic sibling? Repeat the same steps, not new rules every day.

• Use the same short scripts: “Baby is sleeping,” “Hands stay on your own body,” “You can help by…”
• Build shared routines that are quick and safe, like waving good morning to the baby, then moving to a preferred activity.
• Watch for stress signs, like increased irritability or withdrawal, and adjust the environment and demands. Siblings can need extra support during family changes.
