Am I selfish for having one child

[JustMe9]

Am I selfish for having only 1 child? My partner doesnt want more and I would cope well with another child as my first one is such a hard work! I miss my freedom and lay ins in bed in the mornings etc... Is it hard to be the only child? I.e. Ive got a brother but we are not close at all but still I know that he is there if I ever need help. Would it be very selfish just to stick with 1 child? I am in my mid 20s now.

My solo child is happy as Larry. Zero ill effects of being the only one.

I'm an only and didn't like it. I was determined to have more than one child as I think being an only child of an only child is probably not the best. No aunts, uncles or cousins.
It's not selfish to have one though, you just have to work harder to ensure they are more sociable and have a greater network around them. Having more then one for the wrong reasons is worse.
