I put the 3 year old boy I have back in a pullup because of the pooping in the underwear. At the time he was also having way too many pee accidents but that has now stopped and he has even started telling me that he has to go. But never tells me he needs to poop nor tells me that he has pooped - same at home. Parents know they can do what they want at home but at daycare he is in a pullup until fully trained with no accidents of any kind for a month before we do underwear.

Another option for the cleanup is to get the snap apart cloth diapers - they have some that are like a pullup and snap at the sides. At least when you need to change them you can lay them down, unsnap and change like a diaper vice pulling underwear down and having to wash the legs potentially. Expensive to buy but at least washable and great for in the future for outings or car trips even after child is trained when there won't always be a potty right there when you need it.
