My little girl is 18 months and seems increasingly distressed over her nappy, she always pats or pulls at it when she has a dirty nappy but today she has been doing it a lot even if it is clean and dry. She hasn't had a dirty one for almost two days and her urine output seems reduced but she has just drunk an entire bottle of juice. she seems off her food and a little warm. I'm wondering if she has cystitis, got her a Dr's appointment for tomorrow but wondering if anyone can suggest anything to make her more comfortable in the interim?
