A new baby changes the older child's world. Jealousy, regression (bedwetting, baby talk) and attention-seeking are normal reactions.

With reassurance and one-to-one time, most children adjust within weeks to months.

Key concepts

  • Prepare the child before the birth
  • Protect special time with the older child
  • Avoid comparisons and blame

Symptoms and signs

  • Acting younger: bedwetting, baby talk, wanting a bottle
  • Tantrums, aggression towards the baby
  • Clinginess or withdrawal

Causes

  • Fear of losing parents' love
  • Less attention and changed routine
  • Visitors focusing on the baby

Risk factors

  • Small age gap
  • Sensitive temperament
  • Parental stress or postpartum depression

Evidence-based management

  • Involve the older child as a 'helper'
  • Daily one-to-one time with each parent
  • Praise gentle behaviour with the baby
  • Keep routines (school, bedtime) as stable as possible

When to seek professional help

  • Aggression that puts the baby at risk
  • Regression lasting many months
  • Parents can book a consultation first to discuss concerns before involving the child

Frequently asked questions

Should we punish regression like bedwetting?

No. It is a stress response; reassurance helps it pass.

How do we prepare a toddler for a new baby?

Read simple stories, involve them in preparations and avoid big changes like moving rooms close to the birth.
