I have to go back 2 weeks after I have my daughter. I'm a grant funded researcher working off a timeline mandated by the gov't so I don't have much of a choice in staying home longer (if I want to keep my job).
I did... but it didn't last much longer after I started back... mostly cuz I got lazy... well and stress with my bd I dried up when she was about 2 months.. maybe a little older.
