I agree with you. My kids are almost teenagers now, they both were in daycare even though I wasn't even working. We did it for the socialization (I was a young mother and didn't know anyone else with kids) and because we were told that having them in that kind of environment would build up their immune system and get them ready for school. Not sure how true that is, but my kids are rarely sick now whereas it seems half the school is out with the flu and stomach bug. *shrugs*
They both are still in afterschool 10+ years later and they are very well-rounded, polite, respectful, loving young men. They know mama loves them, there is no doubt whatsoever!
