Also, another great option is to have a dad at home. My brothe was a stay at home dad. It was great for their family. His wife had a great job, and my brother struggled with cancer. When he wasn't sick, he was a Boy Scout Leader, baseball and basketball coach, and a great dad.
He died last year and his old Boy Scout Troop and Little League Team both talk about him at his funeral.
He left a bigger impression on kids by being a stay at home dad.
That works too. I was often envious of my wife and wished I could have had the chance to spend so many hours with my children.
My husband stays at home, except for a handful of hours he works evenings a week. He is in the restaurant business and if we had to rely on his salary and benefits, we'd have to live in a box on the street. Our youngest (our only child together) is a very well adjusted happy child.
