Maybe a reward would help. My son used a sticker chart for pee and another for poop(which took longer and more effort). Once he filled in all the spots with stickers, he would get a surprise. He earned it and liked working towards that goal. But having said that, just because she has seen the process and seems to understand doesn’t mean she has put the connection together with how to do all of that with her own body. She may just not be quite ready and that’s ok. Sometimes waiting a month can make all the difference. I would suggest you talk with her about it a lot. Everybody pees and poos for starters and then become more specific later as she becomes more actively participating in the conversations. My son tried the first time when he was 2 years old. He wasn’t ready. We tried again at about 2.5 and he still wasn’t ready and the pressure was becoming a negative for him. So we backed off and just talked about it instead. We made a really big move and decided at the same time as so many changes, we would try at 3. Took him one day and he was potty trained. Poop took alittle longer. Our reward charts helped a lot.

Maybe when you go for a pee it might be a good idea to put her on the potty then and she might copy you, that’s what my mum did with me anyway

And don’t give in. Talk about what a big kid,

If she’s holding it like that then I think I 100% she is ready. Try not asking just saying it’s time to go and making sure it’s at times like right when you wake up, right before nap time (if nap) and meals etc. try even a small treat like smarties every time she uses the toilet and big celebration every time something happens. My first refused toBe potty trained and would pee her pants on purpose and I had her start helping to clean up.
