recommendations where a couple adopts a kid?

Looking for a manga where a couple adopts a kid. Something like 'Kazoku Ni Narouyo' where they raise a kid that isn't theirs and eventually adopt her. I've been looking for ones like this forever, but usually there are only single parent stories and that's not really what I'm looking for. One where a couple raises a kid together as a couple from the start, if those exist!
