Preschool recommendation in River Valley area

My son goes to Little Village and he loves it. I think his teacher is just lovely, and they have nice outdoor space. Others with nice outdoor space in River Valley area include Brighton montessori, Sam's Early Learning Centre on Jalan Mutiara (off River Valley Road, near Great World City) just the other end of Jervois Rd - The Childrens Place, big outdoor space too.
