When to Consult Your Paediatrician

If your baby is NOT doing any of the following, speak to your doctor - Early intervention is key:

  • Not crawling or pulling to stand
  • Not pointing
  • Not saying any consonant sounds
  • Not playing peek-a-boo

Singapore-Specific Advice

The 9-month developmental assessment at your polyclinic checks social interaction, gross motor, fine motor, and language. Babies who are not yet pulling to stand or showing social engagement are followed up. Ask about speech and hearing if you have any concerns.

Remember: Every baby develops at their own pace. These milestones are general guides based on WHO standards. Always consult your paediatrician, polyclinic, or family doctor if you have any concerns about your baby's development.
