I just got an invitation to a "Why Wait - Let's Celebrate! Pull-UpsŪ House Party". The mom that sent it to me said in the message that it is a potty training party for her daughter and all her potty training friends. I have never heard of a potty training party. What is that? I can obviously ask her but it's 10:30 PM so it's not the time ... LOL. Can anyone enlighten me?
