Just had a conversation with my mother and seeking others' opinions (I'm quite open to the idea that she may have a point, I would find it easier coming from someone else).
Gist is, DS started school this term and in holidays spent much time with his 6 yr old sister pretending to a baby - her favorite game. Mum's take is that he's clinging to babyhood and needs to be persuaded to view himself as a grown up boy so that he won't think it's OK to just wee in his trousers. Part of that is apparently weaning him.
He potty trained at 2.5, then regressed after 4 months and wore nappies again for another 8 months (ish), then wore pants but had accidents reasonably regularly through Nursery. It comes and goes. He can go for weeks without an accident then have 4 in a day. Have seen GP to ask about infections - none they could identify. He concentrates hard and seems to block everything else out when something engages his attention. He doesn't seem to notice the signal that it might be time to go to the toilet... or he's too busy and doesn't think it's that important.
At a bit of a loss to know what to do. Feel inadequate for not having him "school ready" but to me the two things are not connected. Am I deluding myself?
