K.F.
The first time my son went on the potty (at 22 months) he pooped, and when he got up and I saw that he had went I cheered and got all excited and he got scared and wanted to get away from it and wrapped his arms around me and wouldn't let go! He hasn't went on it since as he is now scared of it and wants nothing to do with it. I rewarded him with a cookie and told him what a good boy he was, but that didn't do anything obviously so yea that was his reaction! How old is your daughter? Maybe she is still too young to understand what she did or to get excited about it.
