TFB - I think the nappies at childcare have definitely made the problem worse. We went a while without the nappy this afternoon and then tried the nappy again (we had to go out) and she didn't seem to mind. I'll give her a bit of time again tomorrow and hope that helps the rash clear up. We had a couple of puddles to clean up. Like I thought, she's definitely not ready for TT - at least we know for sure!
