"Boys learn how to be men from men, and one of the great problems in our society is that too many boys don't have a father in the house to teach them what manhood means."
Do you have any brothers? Would you feel comfortable signing your son up for Big Brothers if that's available to you? Is there a Grandpa in the picture? You do have options.
I was blessed to have my boys (one son, two nephews that we raised) have a big extended family with lots of uncles, as well as them having their Dads in their lives.
I don't agree that it has to be their blood-Daddy, but boys do need men in their lives. And it can be even worse for us girls! If we don't have a Dad that thinks the Sun rises and the Moon sets on us...we WILL go looking for that love in all the wrong places.
I agree with the poster that said God designed us this way for a reason, but there's no reason NOT to give our kids male/female based families as best we can when circumstance takes the original option away from us.
Be careful. Big Brothers and Big Sisters are infested with homosexuals and sexual predators. Think about it, how many adult men (especially married men) have time to spend with someone else's kids?
