^ Sounds like you had a decent childhood and the grandparents help/support during a time of crisis is fantastic. I actually grew up in an incredibly impoverished household and was an only child, so I'm not even sure how much I personally "cost to raise" ..
Anecdotally, one of my affluent colleagues has two boys and his costs right now include $35K a year on private school. This doesn't include hockey gear and other extracurricular costs. Obviously children of higher income individuals cost more to raise..
