Hi,
I don't have any advice, but would be interested in watching this thread, as I feel we may encounter this issue!
We just started potty training on Thursday but last night, DS asked to use the potty 30 mins after being put to bed. He had had a few accidents during the day when clothed so I didn't really believe he needed the potty when he shouted "Mummy Potty, wee-wee", as he hadn't ever asked before and also he hadn't wanted to go to bed and had been trying anything to not go. I thought this was another delaying tactic.
I obviously couldn't leave him though, as I was trying to get him to call me or use the potty when dressed (and this had been the first time), so I went up, got his nappy down, and lo and behold he did a massive wee in the potty! He was very pleased with himself and so was I. I perhaps stupidly rewarded him with a further 10 minutes downstairs. DH was amused as he thought it was simply a delaying tactic.
I am over the moon DS called me, and that he did the wee, and this morning his nappy was dry, so that's a great sign.
However, I do wonder if he will start doing this even if he doesn't need....
