She was born at 5lbs 12 oz at 2 months she was 8 lbs 5 oz and now at 3 months she is 9lbs 2 oz. At about 2 months or so dr said to give her 24 cal. formula between every feed. To me you might have just as well said give her bottles. She eats at the breast on demand most of the time it's every 2 hours at night and 2 to 3 during the day. But me being me I give her 2 bottles a day one in the morning and one in the afternoon 4 - 4 1/2 oz each. I have noticed her legs are getting more meat on them and her arms as well. So I feel she is gaining weight. I know she is not on the weight charts but I feel since she is gaining weight she should be ok she just does not gain as fast as they want her to. She was 18 in length and is 21 in a half inches long now. She is meeting all her mildstones. So I was wondering what you mommies think?
