L.C.
I have been there. My son was 2.5 when I was due in Sept.(1998) He was a great with the potty, until "baby" started to be the focus of things. He was GREAT with the idea, and he even helped pick things out, and when little sister got here he was great with her. But he wanted the attention too. So he started avoiding the potty at home. Once my daughter was born and she was getting the, "how cutes", and "awwws" he stopped using the potty at school too. Luckily, my children have an awesome dr. and we were able to pin point some of the problems quickly. The more attention he got, the more I let him help with the baby, the less he wanted to BE the baby. Hope this helps.
