DS is 2.4 and is happily dry during the day for wees. He's been using the potty for about a month and we've had him fully in pants for about a week. But, while he's happy to wee in the potty he won't poo in it. Instead he'll do a poo in his pants. I've been telling him every time that he should poo in the potty and he says he understands, but then he'll just poo next time in his pants again.
Does anyone have any advice about how to tackle this problem? He's starting maternelle (like Kindergarten - we're in Belgium) in September and ideally he needs to be fully potty trained by then. The school have said it's OK if he's not, but I'm concerned their patience will wear thin if he keeps pooing in his pants!
Help and advice gratefully received!
