Wow, MrsZ, I don't know if I have anything to add, but I have 4, with the same age gap as you- mine are 8, 6,6,4.
I got a bug about 2 years ago that felt exactly like morning sickness, and for those few days, I really wrestled with the idea of termination.
I just feel so done with the baby years, and excited about the increasing freedom that their growing up will bring. I don't know that it is necessarily selfishness on my part, just that it's time to move on.
We are comfortable, financially, so when I was surprised with number 4, I hired domestic help. I basically had a house keeper 5 mornings a week, who also helped with nursery/ playgroup runs, for the first school year of DC4's life
Despite having a husband who's away Monday to Friday, I found DC4, the easiest, because of all the extra help. Could you afford to get domestic help?
Yes, your kids are a perfect gang- I get that, but they'll make room for another. You sound like you have a very happy family life.
Personally, because of our financial security, large house etc, I doubt I would have gone through with a termination, had I been pregnant, but I would have been majorly pissed off, depressed, sick as a dog, dreading the whole thing.
But, having 4 kids already means you're probably really good at it, you say you love beings mum- if you go through with the pregnancy, you get to meet another mix of you and DH.
I pushed my triple buggy into the park one day, while visibly pregnant with my 4th. I remember feeling foolish for having so many babies, and like I had to explain how amazed and frankly unenthusiastic I was about the prospect of 4 under 4. I was saying this to a woman I vaguely knew, and she looked at me in a perplexed manner, and said "Every baby is a blessing". She was right, of course, and it alway stuck with me.
I resolved to try and be more positive, and not be defensive. We had enough love, a happy marriage, comfortably off, and it would all be ok.
My fourth child was the first one that I put into nursery- I was really ready to get some "me time" back. Would promising yourself that you'll pay for more child care help you to face back into the baby years?
I really get where you're coming from, it's hard to have all those conflicting feelings- hope you're doing ok x
