My daughter has an 8 month old baby who has been ill for a few days with a chest infection. His nappies seem to have been quite dry since being ill. He saw the doctor today who said because he is producing tears when he cries, he isn't dehydrated. We are getting concerned though as tonight, despite drinking water and milk, his nappy still seems very dry. Is it normal for an unwell baby to have dry nappies or should we be concerned?
