I had one like that. It’s SO frustrating. Refused to ‘try’. I could make her go through the motions, so the ‘she needs to be trained’ folks felt I was ‘controlling that child’. But she didn’t ACTUALLY try. She just smirked while plotting where the least washable option was. And then, of course, minutes later she was wet and I could have SCREAMED. It felt so bloody personal. Like I was doing all the right things and she was LAUGHING at How Fun It Was To Make Mummy’s Life A Bit Harder Than It Needs To Be. As if that wasn’t the entire world’s goal anyway. (Of course, she wasn’t really doing that. But that’s how it felt). She’s still exactly the same. If I try and MAKE her do anything, she will dig in so hard.
Nappies are way easier. If she’s reluctant now, and you ditch the nappies, you will be constantly anxious and ‘just try, darling, please’ because in a minute we’re going in the car seat, or will be a long way from a toilet, or the sofa is quite new, or I just CAN’T with laundry today. Spending your evening vaxing the bloody sofa AGAIN because they said they didn’t need to go 14 times and then wee’d on it when you took your eyes off them ten seconds after you last asked is infuriating in a way I can’t describe.
Keep in her nappies until she begs to use the potty. Then be DEEPLY reluctant to allow to her to try again. It will be way easier. Nappies are cheap compared to therapy. Or wine. Or whatever else you need to cope with the phase when they can do it, so long as they aren’t tired, stressed, hungry, it’s Tuesday, on daddy’s less vigilant watch, or you’re out of laundry tabs. In our case it was only a couple of weeks between being perfectly able but refusing to co operate and no ‘training’ required, just doing overnight. And she went straight to the loo and refused a seat. I think she just needed to refuse something. She seems to be a child with a deep seated need to refuse. (Cracking teen though. Doesn’t GAF what ‘everyone’ is doing)
