I too have had a huge happiness increase since having children. I have two, they are the best things in my life. Overall though, I don't think the op problem is just about kids, it may be just down to isolation and loneliness. We need a village, family and social support to feel good. I'm happiest not only when I'm with my wife and children, but also have grand parents and other relatives and close friends gather.
