My 14 month old woke up this morning with a completely dry nappy and I am a bit worried. He has been a bit off the past couple of days, was up most of the night the previous night and is not eating well, although he has drank lots and ate quite a lot of melon and such like. I suspect he might be getting chicken pox as he was at a childs house last week who now has it. Anyway would this be normal if he did? He seems fine, but usually his nappies are pretty heavy come morning.
