I agree with Bassett - we had a bio child when I was 27 and adopted at 38 - so I've seen both worlds and they are different, but not better or worse. It was much easier for me to cope with less sleep in my 20's, but we were broke then and could take as much time off, didn't take yearly vacations, didn't own our own house. I'm more patient now - most days
For me another difference is that all our friends had their babies (1st babies) the same time as we had dd#1 - now they are done with babies so we're kind of alone - well not, I mean everyone loves our baby, she's like everyone's baby, but they all had 2 or three kids where we didn't and have this 11 year gap between the girls.
