That is a very personal question meaning what some of us think may be the complete opposite of what you think and neither side is wrong obviously. Personally, I am expecting my 4th boy and as much as I have always longed to have a girl, I know I am done. This pregnancy has been easy enough up until now (I have 3 months left), at this point I am starting to feel it more. I just don't have the energy I did with the others, especially after running after 3 children already and that includes keeping up with their schedules like soccer for the older boys for instance. I also recognize that I have been treated very differently this pregnancy. I am considered advanced maternal age now and have gotten screenings done they never suggested when I was pregnant the last 3 times. Reality is, the chance for things to go wrong such as autism increases with those in their 40's, even if it's just the dad. (My husband is 41 so this is something that concerned us even this time.) I also can't help but think how old we will be at different stages...when they graduate high school, when they get married, when we might become grandparents Godwilling. Our children don't have ANY grandparents now who can move around well and the youngest is 63. Honestly, looking back, while we are very thankful for the children we have now and can't imagine life without them, my husband sees now why I wanted to start our family younger than we did. He was the one who wanted to wait. Looking back, he wishes he had agreed with me sooner.
Like I said though, this is OUR experience, OUR opinions about what is best for us. From what I have heard for various friends and people online, I don't know that that longing ever goes away completely. The question is, do we give in every time we have it or do we accept we are going to be starting new chapters of our lives? I know I second guessed it for a few days because I LOVE my children, I LOVE having a big family, and part of me would have liked to have gone again and seen if God saw fit to give us another little boy or that little girl finally...but in the end, I realized that even at 36 and in my case, having repeat c-sections, I had to accept that this is the last chapter of babyhood we will be experiencing. It makes me a little sad but like I said, I'm trying to look forward to the new chapters we will be experiencing because I know they will be wonderful too. :)
