DD2 is 3, we had started potty training in March and she was fine with no knickers/ trousers on but would always forget if she had knickers on, she then got poorly so we stopped for a bit and every time we tried same thing couldn't remember with knickers on.
Now I really need to crack it while she is off nursery for the summer but again she fine without knickers, but yesterday she wet herself on the sofa and just sat in it unbothered watching tv. This morning she weed through knickers on the kitchen floor and just carried in walking around....I'm sure she should be bothered by being wet but she isn't.
