When we were adopting the first time, there were two couples in our group who were "older"

The wives were mid 40's, the husbands were 50's.
Our agency went by health - not age...
And the idea that an agency said that emoms don't pick people old enough to be THEIR parents is absurd. My DH is actually the same age as JD's biograndpa (firstmom's dad). In fact, her youngest sister is only 6 months older than JD...And in our experience, age had little to do with anything - it was the connection...
