My LO is 9.5 months and at 9 months she weighed 18 lbs. She has chunky cheeks and legs, but when I lay down with her to nurse, you can feel her ribs. Her doctor said she was in the 29th percentile for her weight and that really worried me. Does anyone else have this issue ? She nurses 7-8 times a day and gets 3 meals of baby food everyday. I don't know if Im doing something wrong.
