Thank you guys! Your schedules are all very similar to how I have structured mine, so it's good to know I must be doing it right!
Right now I am phasing the kids in to get to know them and their routines well, so my first week I have only had 1-2 kids max until July when kid #3 and kid #4 begin. I think I will find that I have less time to fill when there are other kids to play together. 1 kid from 730-530 can be a bit boring! It's hard to go from having a strict, busy job that there is never spare time, to having hours of "hmmmm what now?"! Thanks for all your input. I am going to get some more puppets and simple interactive things to fill the gaps
