I agree with both ladies. I am sure you will be fine so try to relax. Take some time and get the daycare "show ready" and have your contracts laid out so they can read them. If you have any letters of references from past clients or cards with notes in them, I'd have those handy too just in case. It shows that past clients were happy with your services.
I would be nervous too but not because I have anything to hide...it's just natural to be on the defense when someone makes a false claim against you I think. Have a bottle of wine chilling in the fridge and ask a friend to come over when the visit is done. I would want to have a drink and vent to a friend or my husband when it's all over lol
Good luck!!
