The girl is in such a situation: she was born with a weight of 2940, in the maternity ward lost up to 2755. In three weeks she gained up to 3070. The pediatrician says that this is little. He says that if she gained so little, then she lags behind in development. She has anxiety attacks. I can't force her to eat if she doesn't want to. She eats regularly, but in small portions. Is it a problem?
