I see that you're staying in Punggol. Maybe you can bring your child to a paediatric clinic. I go to the one at Rivervale Plaza & the paediatrician, Dr Zainal Muttakin, is very good with kids. My son is 2 1/2 months old now. I would worry, too, if this was to happen to my son. At this age, we must rectify the problem quickly by bringing our child to a specialist.
All the best ya!
