Babysitter Needed For My Children In Guthrie.

I am looking for a babysitter for my nephew during my wedding. He is 4 years old. He is the ring bearer at my wedding so he will probably stay until dinner is over. After that we would like someone to take over watching him to give my sister who is a single parent time to enjoy the wedding. The babysitter would either be watching my nephew upstairs at the wedding venue, or down the street at the hotel. We will determine that later. He is a sweet little boy, but he has adhd and sometimes has difficulty being told no, so we would need an experienced and confident babysitter.
