Any 3rd time moms considered a 4th baby?

So I recently had my 3rd child (2nd daughter) my oldest is 4 and middle is 2. My fiancee and I have talked about big families. He wants to try for another boy eventually (which I keep saying it could be another girl lol, but I don't care). Now my infant daughter is only 3 days old so this isn't going to happen right now but we have talked even when I was pregnant about #4 and that is my cut off I don't want anymore than 4 children. I came from a 3 children home he came from a 5 children home so I mean I see where we both would possibly want a big family (which we have now). But my point is I am at least waiting a year to three years after her. I don't want to get pregnant again so soon (my oldest two are only a 1year and a half apart). But we don't want our children so far apart either so they all grow up together etc.... plus I don't enjoy being pregnant or anything at all but I do love what comes out of it. I'm just seeing what maybe 4th time parents have to say I mean like I said it isn't happening over night but I do think eventually it will we both agree that 4 we could do. I'm just curious that's all honestly
