DS has been daytime trained for a while now (pee since June, poop since January - before that he'd ask for a diaper for poop). These last few weeks have been stressful for him in many ways (DH had medical issues and I had to travel out of town because of this, then we came back and 2 days later DH was hospitalized), and to top things off he was sick with mild diarrhea earlier this week. Since then he's had a million accidents (both poop and pee), like several times a day (he had more than average before getting sick, but now it's ridiculous). In fact, most times he's been peeing his undies, and whenever he makes it to the potty it's because I drag him there. I have caught him in the act several times, I look at him and I just know his look and he'll deny he has to go, hide in a corner and wet or poop his undies. Then he won't even tell me he's wet, and when I notice and tell him we have to go change him, he cries.
I don't want to scold him or punish him, so he won't make negative associations and all that, but I've been trying to be very clear that pee and poop go in the potty and that he needs to keep his undies dry. I also told him that the Automoblox he got as a prize for learning to use the potty will have to be put away if he's not going to use the potty anymore. But I don't know if I'm doing more harm than good with this approach.
Any advice for handling this?
