My DS is 3 and has been "potty trained" since June. He never pees in his pants and has great control. However, recently he has been having trouble with going #2. Sorry for the TMI...It seems like he holds it in for days (he dirtys his underwear without fully going) and then he will go in his underwear.

We have tried rewarding him with a snack that he likes and we make a big deal when he succeeds. I've been giving him more water and apple juice in case he is constipated but then he still holds it in! Lately, DH and I are get frustrated and I feel bad.

I called the Dr already to see if there is a possiblity he is constipated or has something medical going on but my gut says this is a control issue. Any tips/tricks? TIA!
