Poop and Pee!

We potty trained Ty back in October, and he caught on very fast and hardly had any accidents. He even sleeps with underwear on at night. Lately though he's been having a lot of accidents. I don't know if he's just getting lazy or what, but its driving me crazy! The other night we had my Brother, Sister in-law, and niece Bella over. The kids were playing down stairs when we heard Bella yelling "oh no, poop and pee, poop and pee" We all looked at each other and I just knew that Ty had pooped in his pants. Well, he had dressed himself and was wearing little pj shorts and apparently no underwear so the poop fell right on the floor. When Adam and Ryan went down both Bella and Ty had peed in their pants, Ty had pooped and Bella had stepped in it! Ha ha ha...I thought it was so funny, only because I didn't have to clean it up!
