we're slowly potty training, ds1 in pants, at home he'll use the potty and he was using it fine when out and about, I'd remind him before we left anywhere and when we arrived and he'd be happy to go to the toilet with me and have a try, sometimes successful and sometimes not but he'd always have a little sit - not anymore, the past week he's flatly refused to sit on the potty when we are out and then about 5 mins later wets himself, its so frustrating, after a week of this I'm struggling to keep calm, why was he doing so well and is now getting worse??
