I was struggling with what to do with my 3 1/2 year old for school next year (she'll be 4). After reading some of the material in this I decided I will just keep her home until she is 6 and teach her myself. I agree with Donna - 5 is way too young to be in a full day of school - they need to run and primarily learn through experiences and free discovery until age 6/7. The ability to memorize letters does not translate to understanding language. I think people push their young children into a full day way too soon for daycare purposes. I don't think it serves the child. Your son is probably just not ready and that doesn't mean he will be "behind" later. I wouldn't keep him where the teachers label him as "behind." If there is truly a developmental question that is for a doctor to diagnose - not a teacher. Anyway - he sounds like a normal 5 year old boy to me. I would change his school if that is the only option. Or stay home with him or put him with a caretaker who will let him be a kid and learn the way kids learn. I think today people put so much emphasis on "getting ahead." I'm not sure the pressure to get ahead results in anything in the end. I never went to preschool for a single day and started school at 6. It didn't stop me from completing graduate school.
