Is it normal for babies to lose loads of weight when they're ill because Jamie seems to have. It was the first thing nursery and my family commented on when they saw him. His still not skinny but is back on the top of the weight chart when he was way over and his still a long way over for height. Should I be worried or is he likely to put it back on now his better or at least not lose anymore

I was reading about this in the red book today and according to that it's normal for them to lose weight when they're ill but they usually put it back on within 2-3 weeks xx
