I realize this is an old topic, but I just found it. I am a preschool teacher. I own and operate a preschool and after school program in my community. I am amazed at the lack of understanding some families have about what preschool is. To many I'm just a glorified "babysitter" (I HATE that word! it's so politically incorrect!) Preschool is not about sitting at a desk and doing pencil and paper activities. In fact studies show that worksheets are developmentally inappropriate for preschool children. That's not to say you shouldn't ever give them a worksheet to do-they love to do what they see 'big' kids bring home from school. The whole preschool program shouldn't be based around it. We have a church based preschool here that gives all the kids worksheets for 'homework-even 3 yr. olds! The parents think "wow! my child is going to be so ready for kindergarten!" They are so clueless!
The decision on preschool is a personal one based on the needs of the child. If deciding to send a child to preschool parents need to find one that suits their needs. Important things to look for is the education level of the teacher (again research shows the higher the education of the teacher the better the students will do in future educational settings) and the types of activities they do.
Wouldn't it be nice if every time we messed up our life we could press CTRL ALT DEL and start all over??
