I'm guessing you don't have children.

Children being alone at home vs. being with lots of other children in daycare has many benefits.

First, over the years I've seen a lot of kids that stayed at home with mom that were not socialized well at all. Being in a group is how we evolved. It's natural and normal. Being at home with one parent all day is not normal at all.

Aside from socialization, being in the "home bubble" doesn't do a child's immune system any good. They need to be exposed to lots of stuff early in childhood to develop a strong immune system.
