My baby boy is 65days old. From last 30 days we are facing problem regarding his feed intake. We give him top feed nan pro 1 by spoon. As soon he takes 8-10ml milk he falls asleep and only after burbing we are able able to feed him next 10ml milk. This is becoming a big problem as feeding him 75ml takes around 2hours. Why he requires so much of burbing at very short intervals. As a result his feed intake has declined. Only 360 ml within 24hours. His weight at present is 3kg.
