We've tried putting 'big boy pants' on son who is 2.5 for past couple of days. If we remind him & catch him in time he will use the potty but other than that no luck. He's wet his pants a couple of times & not even noticed. Do you think he's just not ready? If he's not it's no big deal we'll try again in a few months but don't want to give up if this is a common problem at first.
