The baby is 6 months old and has been in the hospital for two months now. The weight hasn't changed. 7600 lbs at birth with a height of 67 inches. We take 2 cm per day. Doctors say it's hot right now, but they will catch up later. I'm worried, maybe something is wrong with the milk. Maybe not enough fat in the formula. We've been feeding him a little bit at a time.
