I'm sure some do, but my question is more can a child with a SAHM go without preschool and be successful in pre-K and kindergarten. Say for example a set of twins who have each other all day, and 4 older siblings of various ages who have friends over a lot, and who get some other interaction with similar aged children outside the home for free play a couple of days a week, with an educated mother able to teach the basics of numbers, letters, good behavior, etc. Is preschool a must have for all children, or can a good SAHM skip it? What would a SAHM need to do at home in order to successfully prepare her children for either pre-K or kindergarten without sending the kids to preschool?
