She should be fine! Babies just kinda eat when they want to, as long as her weight stays healthy & where it should be then I wouldn't worry! (:

My baby girl has been a finicky eater from day one. She has her days when she barely eats. Even now at 7 months she only eats 4 oz. every three hours. The only difference now is she eats baby food too. I discussed it with my pediatrician and told her what she was doing. Her conclusion was she is still growing and gaining weight so she isn't concerned unless she quits gaining weight. So we still fight every meal, but she is fine so far.
