I haven't been in the business long, but I can tell you one thing I learned here; it has to be about the children, not the parents.
My dcf's wouldn't care if I let their children sit in front of the tv with Doritos and Mountain Dew. But I care. I care about the children. We are outside a lot. We do a lot of free play, creative thinking, problem solving. We eat good, wholesome foods. We learn manners, self care, how to listen to instructions. We get messy. We go to parks, children's museums, library story time. We have fun. That is what I want to give my own children and just drag my dckiddos along for the ride.
The children enjoy it and so I enjoy it. It's not to say that the parents don't appreciate my efforts, it's just that they really don't care one way or the other. But I care. That's what counts.
