I'm potty training my 2 1/2 year old son and he's doing great peeing on the potty. He just WILL NOT poop on the potty! He got constipated last week and I had to give him a glycerine suppository. Well, that worked, but he just will not poop on the potty. I've tried giving him M&M's, offering ice cream, a toy, etc. Nothing seems to work. He's still kicking butt with the peeing, it's just very frustrating that he won't poop. I think I'm just going to back off for a while and let him figure it out on his own. I don't want to stress him out and have him get mad and stop peeing on the potty. Any advice??
