My son is 5 months old and he is very underweight, i have taken him to the doctor and they told me that i need to start waking him up every three hours at night to feed him along with daytime feedings. He has started gaining some weight, eating a 6 oz bottle every three hours but the last couple of days he has startef eating less, like only 3 or 4 oz at a time and it is really starting to worry me. I need to know why he has started eating less all of a suddenView Thread
