Girls, hello! ? Recently I've been really worried about the baby's weight. The doctor scared me at 35 weeks that he already weighs 3 kg and could be born 4 kg at delivery (like a big baby, it will be hard, as I understood). I read all sorts of stories about big babies, ruptures and so on ? I gained 17 kg during pregnancy, is this much or normal? Should I worry? Now I eat less ?
