Woo, am on laptop so will be able to do lovely long reply :)
Lee - I love 'I want a conversation' :o the things they come out with! I caught Noah drawing on the kitchen floor the other day and told him that we didn't do that... his reply was 'Granny draw on floor' :o I texted my mum to ask her what she'd been teaching him 
Definitely brave attemping potty training, blathers! I'm also not going to go for it until the summer, although we do have a toilet seat and stool for him as he started asking to sit on the toilet, but we're not pushing it at all and only when he asks to go do we sit him on it. I need rosa to be a little more self sufficient before I really start to try with him, if we start when he's 2 and a half, she'll be about 10 months :) Just got to cross my fingers that her seperation anxiety won't be too bad at that point so I can happily take him off to the toilet! I also don't want to use a potty, although the toilet seat we've got is also a portable potty for when we are out in case we can't get to toilet in time.
I'm also thinking September might be good for starting pre-school. The one we'll use is next door to the children's centre we use quite a lot and so I'm familiar with the staff who sometimes bring the kids through for sessions at the children's centre. I think he will love it, he has no worries about leaving me at all, he's very confident and really loves playing with other older children :) WRT potty training though, I did ask and they say they are quite happy if the children aren't trained yet, they will just follow with what the parent wants to do :)
Anyway, hope we're all ok :)
