Play & Activity Ideas

  • Introduce board books - Babies love high-contrast and face images
  • Practice sitting with cushions around for safety
  • Sensory bags (sealed ziplock with gel and objects inside)
  • Outdoor walks in pram - New visual stimulation

When to Consult Your Paediatrician

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

  • Does not roll in both directions
  • Does not reach for things
  • Cannot bear some weight on legs
  • Not babbling

Singapore-Specific Advice

Start researching the Baby Bonus scheme if you haven't already. The First Step Grant (SGD 3,000) for the Child Development Account (CDA) is available for all Singaporean children. CDA funds can be used at approved childcare centres, medical, and educational institutions.

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.
