Us, too, AnyFucker.
In our case, too, it would not be a wise decision to have more no matter what happens.
I experienced increasinly worse ante- and post-natal depression with each child. I'm also nearly 40 and tbh, for me, I feel too old to cope with another pregnancy. I had our third at nearly 38 and found it much much much harder on my body than even when I had my first at 32.
DH appears to have an inherited form of disability.
We didn't have any success with any other methods of birth control that we could use reliably.
A lot of people say, 'Well, men can keep fathering children later,' but can they support them? Because to us, that's really important, and the reality is that if I dropped dead tomorrow, DH will have enough on his hand trying to feed and bring up three.
If he drops off tomorrow, I don't want anymore. Ever. Don't care if new partner or whatever. It's just a no, I'm too old.
