Well, I'm really glad you have a long list but I think as we get going well in the business we really learn how to screen during an interview. The first year you tend to take in families who you shouldn't have allowed in the door. Don't get frustrated, just tell yourself that you deserve better, ok?
I'm flexible and tend to go with the parent's wishes, so if they want to keep their baby on a bottle until they are 2 or some silly thing, that's ok with me. I do wean them off their soother here before the parents do it at home and I do insist that parents respect my schedule regarding naptimes, meals, etc. That's why I made a rule that dropoff must occur before 9am and pickups must occur after 3pm because we are going outside shortly after 9 and I'm protecting the naptime until 3pm.
There are some things I won't be flexible about, like naptime/quiet time because I work such long days and I need a break. But there are a lot of things I'm very flexible about because everybody parents differently. As long as they ARE parenting, I'm happy.
