Can you share your thoughts?
DH and I have not begun having kids yet. Been married 4 months so far!
My husband and I initially thought we'd just have one kid, but kind of keep our options open from there. And our first was a really high needs baby and we thought she would indeed be an only for a long time. It took us 6 years to feel interested in having another, and that one was born 7 years after the first.
My advice would be to take the babies one at a time. You don't have to decide how many right from the start - particularly between 2 and 3. Having an only child might require a bit more discussion. Have you and your husband discussed this? Are you pretty much on the same page or are you feeling differently about it?
Your idea of the right family size for you may change once you're in the thick of it - and then it might change again!
Good advice above. Take it is one child at a time. Your feeling will likely change as time passes and your already present children age. I will say, I was an only and know that having an only child is harder in some ways than having two or more. Easier in other ways, of course, too.
