Thanks for the advice. I know it's all boundary testing, I just wish we could move on from these specific few things.
He's kind of close to potty training, in that he can hold a wee and choose to do it on the toilet. He just has no interest in doing it. He will sit there if asked, especially with someone there with him (1-1 attention is a winner anywhere) but he doesn't mind nappies and doesn't care if he's wet or dirty. In fact he's significantly harder to get to lay down for a nappy change when he's dirty.
The health visitor recently said I need to train him soon "before I miss the chance". I was all nervous and spent a couple of days trying to convince him. Then realised I didn't get what she meant. No child stays in nappies forever just because they weren't potty trained at 2.5?
DD learnt to crawl yesterday. Well, move with purpose. It's not a very elegant crawl! I think my life just got harder didn't it?
