The stories of abusive forced educational training make me shudder, some of that motivation was behind the reason GS9(GS stands for grandson) is with us.

I know this is just semantics, but I'd like to point out that a hothouse is a place where tender seedlings & plants are protected and nourished to grow to their full potential. The seedlings that eventually will be moved outdoors have to be carefully acclimated to the harsh outdoors. As an analogy for childrearing, I think hothousing is good.
