My dd has been potty training this week, doing well when she has nothing on her bottom half, lots of accidents when in pants/clothes, anyway, today I told her off for slamming a door in my face and started to sit her down for time out , she was wearing trousers at this point, I was talking to her and she looked like she was straining then ran off up the stairs, trousers soaking wet! So I got her and started to strip her off to sit on the potty, with her wriggling and making it difficult, just as I got her trousers off she bent her knees and very purposely squeezed out a big wee all over the floor - think crazy eyes in the first season of orange is the new black! 
I have to admit I cried at this point, I feel like she is naughty for me and behaves for her dad and others, I actually thought 'she hates me'. I know she doesn't. Bit she is so. Bloody. Defiant I think it's going to break me. I suppose I'm just posting to see if anyone has any tips, re potty training or how to deal with toddlers who really don't give a shit!
