You do stop feeling that way. I didn't think I ever would and I often said I wonder if there is a switch that just turns off inside you when you realise you're 'done' because I thought those feelings would never go away! But after the kids started getting older and moving out of the baby stage I realised I was feeling more and more like I was done and now I don't feel like that at all. Certainly there are times when I remember the way it was to be pg or give birth and even certain smells bring back memories, but now they aren't painful memories that make me jealous, just pleasant ones where I can think about how special it was and I'm happy with that.
