@beauty151 yes it did. By the time she was eating solids I had to add more fat into her diet because she was still a little under weight. Now shes 10 years old 5'4 and one healthy and awesome girl. Shes still allergic to milk but her Dr allows mozzerella cheese because its low in lactose and Greek yogurt. They also have lactose free ice cream.
My daughter was like that and found out she had severe acid reflux and she was allergic to milk. She had to be put on meds for acid relfux at 1 month old and switched to soy formula.
