Interesting.
When I was divorced, my kids were 9 and 4. Their mother and I divided the children's time 50-50. Now the kids are grown and on their own. It is my observation that EVERYTHING mentioned in this article is 100% right on. It is amazing to see a study which actually gets it right.
By the way, I remarried, created a moral, Christian home, and had 2 more kids which were also 5 years apart, just like the first two. There was one boy and one girl each time. These two are now 8 and 13. Just like the article said, the results with these two are excellent and reflect consistent rearing by two parents who love and support each other. Once again, based on first hand knowledge, the findings in this article are exactly right.
