Question: what is the ideal age for preschool?
Answer: How old should my child be when she starts? Most preschools serve 3-, 4-, and 5-year-olds, and many kids begin at age 4. (Some preschools will start accepting children at around 2 1/2, but that doesn't mean your child will be ready when he reaches that age.) You can choose from a part-time schedule or a full-time one.
