The whole lonely only child assumption is just a myth really. Many non-only children re lonely, and many only children are not at all lonely. There's lots if factors involved regarding happiness, loneliness etc. I can do a lot with DS that I wouldn't be able to do with 2, and that will be true in future too especially regarding travel etc. that would cost that much more money with two or more kids. I find one child is a nice balance for me. Two children would take over my life!
