Dd(19mnths) had blood in her nappy after swimming yesterday afternoon. Dh had them while I was at work in the evening and when I got back noticed blood in her dirty nappy in the bathroom ( men). I couldn't tell in her overnight nappy because it was a pampers (other nappies reusable)and the stupid green lining made it impossible to tell what colour it was. She's done one wet nappy this am and it appears to be ok. Should I think she's had a UTI that's passed or should I get her checked out?
