I said $30 an hour because I would not work for a wage that equals what I'd be paying for childcare, it would need to be substantially more to be worthwhile. I'd rather be with my child for those years than working 40 hours a week just to pay someone else to watch them.

Career growth potential is the only factor, and I won't judge anyone either way. People should make their own decisions as to what's more important to them. Some will value their overall careers more, and some will value that time with their child.
