Hi Sarah, I want to say my daughter is very stubborn in the last week she has decided to just do poos an wees on the floor instead of the toilets or potty
Oh no! I'm really sorry that this is happening. Would it be worth speaking to your health visitor or, school nurse or pediatrician? Just I think you need support to help overcome this. Also you may be able to get support from this charity too; https://eric.org.uk/potty-training/problems/
It sounds more of a behavior issue more than shes not willing or able to potty train. I know these kids sure pull at our hearts. The eating thing is totally normal. Kids are picky, they find foods they like and will only eat them. I would reach out to her doctor for advice. Hang in there and be easy on yourself.
Firstly, how are you? I noticed that this was posted 7 days. Would you say that your daughter is strong willed? x
