I don’t think children should always have 1:1 supervision, but in my experience and my wife’s experience (as parents of three singletons) there are things you can do with your child on a one-on-one basis that you just can’t do when you have to divide your attention among kids. And some children handle the whole “OMG someone other than me is conspicuously not the center of my parent’s world” situation worse than others. So I think that the program directors have a right to declare that certain classes require a 1:1 ratio, especially when the kids in question are two or three years old.

I understand that “hire a babysitter” is not a viable option for many parents, but, heck, there are a lot of parents who can’t afford to spend $175 on a class, either.
