I grew up in a family with three children and it was good but I think four would be even better. Before I got married someone asked me how many children I'd like to have and I said four.
My husband, a local Hong Kong Chinese guy, was like "Whoa, whoa, whoa...four?!" Before we were married he used to say, "I want to live in a 'two-person world'" which is a translation of a common Cantonese saying which means I don't want to have kids. However, those were just his initial feels and as he grew up as an only child he always longed for a sibling himself and felt Hong Kong was quite lonely for him without one.
So, our pregnancy with our son was unplanned and almost everything about the pregnancy, birth and aftermath was excruciatingly difficult. Even today, when I imagine going through it again my entire body tenses up.
But, the husband who once wanted to live in a 'two person world' fell totally, head-first in love with our son and with fatherhood and if it was up to him alone we would already have a second child and be possibly working on a third--even though he knows how difficult everything was with our son.
Initially the concept of adoption was really hard for my husband to get his head around because adoption doesn't have a really strong cultural connection to Chinese culture--usually if children are adopted (historically) they are adopted within the family or among close neighbors and those children are never told they were adopted--it becomes a secret. Obviously, this is a huge difference from how things are done where I come from. But, now, after meeting several families that have adopted children and talking with some adults who were adopted as children, my husband has come to a different understanding of what adoption means so that could be a very viable option for us in the future, I think.
