My 2yr DD has had temps over night - peaking at 39 but comes down with calpol. She woke this morning with a wet nappy. Since 6am she had drunk and eaten breakfast and lunch. I've just been to change her nappy as I've noticed it hasn't looked full - and it's bone dry. Is this a coincidence with age or would you get her checked out? She has never held it in before. It's been dry for 6 hrs. I'm now offering juice.
