I've raised two, and they are rising their own.
Costs have increased significantly in the past few decades.
If an extra 500+ a month isn't enough, then you are overspending for no good reason!
The only after school care available in my community costs around $400/mo. I'm in a rural area, so it's probably higher in cities.
Daycare may be cheaper now due to the $10/day thing, but I'm not sure how many spots are available.
Swimming lessons are $200-300. Sports typically run for a season, but they start around $200. We've got our kids in "cheap" sports, but even then, costs add up.
