DH and I met when we were very young and have 2 DC (twins) who we also had very young. DC are now 12. We are in our early 30s and have worked hard to get to a place where we are financially settled. We have bought a house, got married, both doing well in our careers and have savings behind us. I would love one more DC, I feel like we are finally in the right position to have a planned child. Would it be madness to start again with a 12 year gap though? Or unfair on existing DC? I’m trying to arrange my own thoughts before speaking to DH about it.
