I thought I was done after my second, but here I am pregnant with my fourth
I have relatively large age gaps between all my kids, so starting from 'ground zero' this time was a big decision to make since my oldest will be very nearly 13 by the time this baby gets here. But my situation is a bit different in that I have a blended family.
I have three children from my first marriage (12, 8, 3) and my now DH has one from a previous relationship that is the exact same age as my youngest. They are only 10 days apart, so it's exactly like having twins. I've been in his child's life since before our babies' first birthdays so I've been here for all of it.
I was done, done, done when I met him and he didn't feel like he wanted to have more than one himself. I mean, together we already have a large family! But the longer we have been together, the more the idea of 'one of our own' had begun to plan itself in our heads. I didn't have baby fever, but I constantly wondered if I would regret it, 10 years from now, not ever having one with him. Eventually we decided we would regret it and it was time to go for it. I'm older than DH so it was more imperative to me that we do it sooner rather than later as I did not want to be in my late 30's by the time we decided to complete our large family.
All of that to say, I do not think I will miss this stage of my life. I already felt done before I decided to give it one more go
I do have very easy pregnancies and deliveries (so far!), so I have no complaints in that regard.. but I know I will not have any more pangs once this is all said and done.
