DD1 has been dry since about 2.5yo apart from a few normal accidents. Now she has suddenly started wetting every single day at school or at home and I am beyond frustrated with it.
We tried ignoring it 'oh never mind everyone has accidents' type thing, then when it was obviously happening every day we put spare clothes in her gym bag but she won't change herself, will just sit in wet smelly clothes all day
we have spoken to her teacher and TA, started a star chart at home etc. Every day we have the same conversation about the importance of using the toilet when she needs it, staying dry etc to no avail. She says she doesn't like the school toilets as they're dirty but this was not an issue at all last term.
I am honestly so cross and at the end of my tether with it. Today she STANK when i collected her and it turned out she was soaking through and also had failed to wipe properly after doing a poo and had poo all over her too, had to shower her down to get it all off, so disappointed in her 
. All this evening i've been asking her 'do you need a wee?' always she says 'NO MUMMY!' like I am being an idiot, but come bathtime she had wet through all her clothes again. I'm ashamed that I have totally lost my temper with her in the last week, it just seems ridiculous and actually wilful on her part.
Can anyone advise how to a) help her stay dry somehow and b) help me to stay calm and deal with it better? I am BEYOND CROSS at the moment which I know doesn't help 
Oh, and yes I have taken her to the docs and there is no UTI
