Pre-school is glorified baby sitting that you pay too much money to. There’s nothing much a child can learn that you as a parent can’t provide in the home setting. I am reading that you may be considering shoving the big guy off to preschool because you just had a little one and may be feeling overwhelmed with 2 kids to care for. If that is the case, a child care center would do the part, or maybe hire a part-time mother’s helper until such time as you’re able to cope with the 2 kids.
