I joined this group when it started and have been kind of MIA ever since. Work and my crazy toddler have consumed my life for the past... how many?... months! So, first off... Hi again!
My daughter is 20 months today. Can't believe she is almost 2. Where did the time go? I work with special needs kids and today we had a beautiful little 8 week old girl come in the clinic. She was so squishy and sweet. Thoughts of "I could do this again" and "oh I just want to squeeze her" came in my head.
We had a difficult time getting pregnant and staying pregnant... then I had a miserable pregnancy... labor and delivery was awful... and her first year? That was a nightmare! Let me clarify... I do NOT ever want to do it again. Under any circumstance. I am 100% OAD!
But do any of you have those pangs of, "maybe I could do this again". Even though you KNOW you are OAD? Am I absolutely crazy?! I can't talk with anyone else about this because they'll start the whole "you should just have another" debate. I figured of all people, you ladies would understand.

Re: oh dear...
Welcome to the board!
Not often, but my sister just had her second child, and I thought how nice it would be to have two children, but then I know how good I have things right now. DS starts kindergarten this month and we can afford private school, a sitter for date nights, I don't have to share my body for nine months and then for another year with nursing, etc. We would have to pay for child care for the new one AND private school for DS, since I would not resign to SAH like I did with DS. I also turn 40 this year and I feel like I'm on to the next chapter of my life.
I experienced all of that and I enjoyed it, but I don't want to do it AGAIN---and have our finances unnecessarily stretched to provide for another family member:-) Our family is already great the way it is.
But then, right around when DS turned 2 this past December, that little thought popped in my head... Oh, I could do it again; DS would be a great big brother; I would be better prepared this time... Every negative that I had thought of before suddenly became a positive or insignificant. DH was still in the OAD mindset, but he said he would not deny me a second if it's what I REALLY wanted. So I have been thinking on it. And truthfully, for these past 7 or 8 months, I have not consistently wanted a second. I have had days or even weeks where I can't believe that I'm not pregnant and I research hospitals and midwives. But it always subsides.
A friend told me she had heard somewhere (old wive's tale) that babies lose their baby smell around 2, and the itch to have another starts up. That's what happened to me. But it's gone. I was never 100% convinced to have a 2nd -- probably because I WAS 100% convinced to stop at 1, lol. Babies are cute but a lot of work. And I do think DS would be a great big brother, but I also think it would inevitably change him; and I can't know if that change would be good or bad. And so I think we'll stick with the good that we've got
I think I've had baby fever once- and it lasted 4 seconds. I'm SOOOO OAD, that I just don't get those feelings. I don't have any desire, maybes, etc. I just don't want it. When I see a newborn, my first thought is "UGH. Thank goodness *I* can sleep tonight!!!"... then I think the baby is cute as a second thought
What helps is to sort of envision my life both ways -- and being OAD always comes out on top. So that's what I'm going with. And if I "change my mind" once it's too late, I hope I can forgive my younger self.
Also, there's a difference between nostalgia and wanting a second. I get nostalgic. But I know that having a second WON'T be the same as having my first again. And then I just try to cherish this age as best I can.
