In our area, I am not sure if it is the same in all, children have to be turning 4 by December in order to start JK. My daughter's Birthday is in Feb so she will be over 4 1/2 when she starts JK...I think this is one of the reasons I want to do a preschool type program since I will have her home so long and want to teach her as much as I can....I don't think I would start with a daycare knowing I would have to find alternative care at age 3 but I totally understand where you are coming from as I feel around that age they do get bored if they aren't being actively engaged. I think saying I can take 2-4 year olds would be easier since I would have them until they go to school and running a program geared to teaching? I know a few people that said they would pull their 2 year old from current daycare where there is no structure and put them in a program that was more learning based.
