Im asking mums (and dads) who have said enough is enough kids wise.....does the feeling of not wanting anymore ever go away?

Id always planned to have 4 kids.
2 girls 2 boys.....sure thats in my fairytale world where things go as planned

Through my entire pregnancy with Zachery, DH and i said that he would be our last. My body has been through a lot with 3 very close pregnancies (which for the record were all planned and i wouldnt have it any other way),i suffer PND and didnt want to see me go down hill yet again when ive been going so well, we thought its now time to enjoy our 3 kids we have been blessed with and watch them grow up.

However......DH is now saying that maybe #4 will happen. I mean id love too...and i wouldnt think twice in saying YES.....but....once #4 came (IF #4 happens....this is all hypothetical atm).....will this 'Hmm maybe another baby' feeling will return?

I know id love another one...but right now theres just to much to consider....new car, financials, the age of our children and the girls would have to share room (and its a pet hate of mine).

I think my main hold back right now is the car situation.....other then that the rest is easy solved
