Disagree, within the timeframe of this topic. 0-6 months is basically all about the bond between child and parents. Sometime after that, sure, a requirement to socialise comes into play.
Therefore, it is more selfish to raise your child yourself than to have an expert to do it for you.
I shouldn't have to disclaim this by argument by saying that I'm not making a serious recommendation to anyone, but because parents are so defensive and irrational when it comes to how they raise their children, I feel that I must. I don't have kids and don't plan on having kids, so this is merely an intellectual exercise for me.
