Why do you want to have just one kid? Maybe if you explain your point of
view and all the reasons of not having the second child, your husband will
think about pros and cons of this decision and he will accept this in time.
Positive thing is that you definitely will have enough time to do all
sorts of things with your child. He will not occupy you too much and you can
keep on working in your usual schedule.
Though, I think you need to consider all aspects of this choice. Maybe
someday you will want another child and your husband has to wait until that
If you do all the hard work, your husband must let you raise just one
baby or start to be supportive.
I have a sibling and we are very close, so I cannot really say that it
is not that important.
However, the choice is yours. Having one child is not that bad.
@SMac2013 I don't know if this will help, but here are my thought and opinions. I am currently pregnant with our first and have decided it will be our only. There are a few reasons why we made this decision. I think one of the main reasons is that I really don't like kids. Funny, right, that I don't like kids, but really wanted one. I just don't like lots of kids all at once. I'm usually fine with one or two alone. Another factor is our ages. I'm almost 36 and my FI is 43. I know that I would not be able to have two kids close in age. I just don't have the patience to deal with a baby and a toddler. So if we waited until our first was in school, we'd be too old to want to start over again with another baby and then chase after a toddler. A third reason is financial. Kids are so expensive. We're living on my FI salary alone, mostly so I can stay at home and we don't need to pay for day care when the baby comes. I never made much in my job, and if I were to go back to work, my entire salary would be spend on day care, so we would still be living on my FI's salary alone. We just won't be able to afford a second child and feel that it would be unfair to both of us as well as any kids we have to increase that financial burden.
I'm not advocating either having one kid or having multiples. I'm not saying people who are not financially well off shouldn't have multiple kids. I'm not saying older women shouldn't have kids. Ultimately the decision is up to you. I'm just laying out the reasons my FI and I have decided to only have one.
