This is one of the best arguments for "It takes a village" I've seen.
Guess what. Daycare is the modern version of The Village when it comes to raising kids. So are babysitters, and grandparents, and godparents, and friends, and teachers.
Spending 24 hours a day with your child may make YOU feel like a great parent- like you are 'there for them' and like 'no one can do it like you can.' My theory though, hate to break it to you, is that you might actually be missing out on doing something amazing for your children... giving them adults. Lots of them.
