My dd who has just turned three, has been dry during the day for a few months until about three weeks ago. Now she just stands there and does it - 12 times a day.
Her temperature isn't up, as far as I can tell her urine looks normal, and I've tried asking non leading questions to find out if urinating is uncomfortable - she says not.
We haven't changed routines recently, and we've tried star charts / removing things she likes.
I would be absolutely positive its something medical if she didn't have this "Mona Lisa" smile - and she didn't go all morning whilst we were out at ballet then went 8 times in 2 hours when we got home.
I've has so many BMFH moments recently (first word rhymes with witch, rest of it is mother from hell) that I'm really starting to feel low about it.
