Hi, my dd is almost 20 months old. She was in hospital recently and they weighed her. She is 10.3 kilos which is 22.5 lbs. She is quite thin but the nurse said she is well within normal weight for her age. The thing that is bothering me is that she was this weight 5 months ago. I know children grow more slowly in their second year and that they thin out when they start to walk but shouldn't she have gained something in all this time? I spoke to the nurse and she checked her iron levels which she said were excellent and that she thinks dd is fine and not to worry. Can't help being a bit concerned though. She has gotten a lot taller so she is growing, just not filling out.
