ISO: A preschool for my already-potty-trained 3 year old boy. We live in South Temecula and would love to have something near here for drop-off/pick-up convenience. I need Tues- Fri 9am-4:30 or 5 pm. Anyone do this? I can't afford to pay this crazy $200 a week like some of these places want, but do want a safe learning place for my son. Any advice?
