Is it normal for them to regress??? DS was doing really well, was even standing on his own and peeing. Even pooped in the potty. The last few days he is just refusing to go. He makes every excuse in the book...it hurts, he doesnt have to go, he's scared, etc. and throws a fit.

I've tried bribing him, forcing him, soothing him, singing, whatever I can think of. Any ideas you can give me?
