I have three kids, and my big regrets are not starting earlier and not having more. My wife and I would have liked more, but it just didn't work out.
Same here, but with 1 established and 1 on the way. I feel like there's room for another after the one currently in the oven but I don't think it'd be particularly fair to put pressure on being pregnant close to 40.
Why did you want more, by the way?
