My oldest dd is 3 1/2 years old. She has a history of her misquito bites getting infected, and we think she's allergic to them. Well today we had to take her to the doctor for another infected bug bite and when they weighed her I was shocked to see that she's only 22 lbs. She was stuck at 24 lbs for over a year, and now she's lost weight. The nurse said it's because she's getting taller, but she really isn't that tall. She's the height of a 24 month old, and she's 41 months. I don't know what to do. She eats all the time, loves food, but just can't gain weight. Does anybody have any idea of something I can do? I'm going to call her pediatrician tomorrow and see if maybe we should have tests run. (we had to see a different dr today because hers isn't in on Tuesdays).
