A sticker chart is not going to make any difference to ds. He would just look blankly at it. I can't offer him a toy as a reward, he won't be bothered. If I mention potty/poo/ wee more than once a day he throws a hissy fit.
With other things you can kind of insist, despite tantrums. But I can't physically make him sit on the potty, and would imagine this to be counter-productive anyway.
He is 3.2. The worst thing is that his one year old sister has been weeing on the potty since her first birthday (not training her yet though).
I don't know what to do. Any ideas/hope?
