Potty training

We are attempting to potty train Lucy. She has a potty which she regards as a toy, so spends a lot of time with it on her head or using it as a megaphone. She's sat on it, but not managed to do a wee in it yet. We had a little accident the other day; Mum and I were inside and Lucy was outside in the paddling pool and freely roaming around the garden, naked. She came over to me and said "Bo", so I asked her if she needed a poo, she said "Na", and wandered off. 2 minutes later, a very embarrassed and ashamed Lucy came over. I cleaned her up and sloshed dettol over the garden and the paddling pool, and we had another go at sitting on the potty.

I think she's not ready yet; Elsie, her best friend, is ready, as she can tell me when she needs the potty, and sits on it without a fuss. Oh well, Lucy will learn that she needs two different words, one for yes and one for no, and saying the same word for both, is confusing.
