Melissa, congratulations on your pregnancy! I'm only planning on about 8 weeks maternity leave (I took 12 with baby #1), and already it's killing me to think of going back to work. I think it's something we think about/deal with/worry about every day of our lives, readjusting a little bit each day.
I'm crossing all my fingers that I'll be able to cut back to part-time so that's helping me a bit, but I know that isn't a option for everyone.
I'm wondering, too, about how to cope with 2 kids (yikes)!! I've heard that yes, it IS just as exhausting, but somehow we just manage, like we did with the first baby. Still doesn't seem possible, though, looking at it from this angle!
One thing I realized recently: You know you always wonder "how will I love this next baby as much as I love the first?" I know it's a silly question, but I figured something out: There is one additional person to shower the new baby with love, and that is the First child! Baby starts out "ahead" in the "who loves me" department.
