Time-out for a mommy-related rant

I have listened to women complain that stay-at-home moms don't get the respect or admiration they deserve. Being a stay-at-home mom is hard work. Then I hear the flip side...women who think paying $600/month is too much for childcare. Presuming four weeks in a month, that's $150/week...which works out to $3.75/an hour (based on a 40 hour work week)! How much IS it worth to make sure your child is happy and healthy?
