Hello Doctor, My son is 15 months old. Problem is some days he eats well and some days he doesn't eat. Even though he eats well like rasam rice and 1 full egg. He needs milk(formula milk- Dexolac) like after 1 to 1 and half hour later. Everyday after he sleeps from night to until he wakes up he drinks milk(formula milk) like 3 times like need to give every 3 hours.  Is it fine Doctor? My friend said that her 16 months old daughter eating and not drinking milk in a day and only having milk at night that to 1 time. Please suggest. Thank you.
