I've had two girls and they were 6.7 and 6.1. Everyone's warning me that because I have a boy he will be bigger. Is this crap or is it true? I'm 35 + 4 and need to think about getting some blue baby grows rather than pink (although do have white so not desperately worried). Its just that if I were expecting a 6 pounder again I would be buying Tiny baby but if its gonna be bigger..... So if you have both boys and girls in your family were the boys bigger babies and by how much?
