I would never in a million years open this pandora's box. Asking questions like these leads the parent to believe that they have a say in how I operate my home and daycare. Quite frankly, they don't.
I have been doing this long enough to know what works for me and the kiddos.
If a parent wants to come and run my daycare for a week without any assistance to get a feel for it BEFORE providing some suggestions... by all means.
