Just out of curiousity, which alternative are you recommending? Celibacy into his 30s, abortion, or agreeing to a bitter, loveless marriage to his ex for the child's sake? (The benefits to children of a 2-parent household are amply documented, but that presumably is based on a strong majority of
happy 2-parent households where the parents wanted to be married!)
Life happens. The situation may not be the ideal, but conscientious, loving parents can make it work. Here's to a long, happy, love-filled life for the little fella. Oh, and John Hannah recommends wrestling practice as soon as possible.
