My goodness, how awesome! I had four months off after the birth of our daughter and it was soooooo wonderful. If your employer is willing to let you work from home say beginning 8 weeks after until four months or so, that would be absolutely ideal and allow for some really nice bonding with your new baby. I will tell you that once our daughter arrived on the scene, I completely rethought working full-time, I was just so attached and smitten with our new little creature that I had a very, very hard time going back to work. I think the night before I went back was the worst night of my life, I balled the entire time and almost didn't go back. My husband didn't know what to do with me, but those mommy hormones really got the best of me. I did go back, because I had promised that I would, but I immediately began looking for part-time work -- and found it. I worked 20 hours, four days a week for 5.5 years and have never regretted that decision for one second.
So that's my story ... everyone is different, but if you have such a wonderful work site and you are so inclined and can swing it financially, perhaps an altered work schedule going forward after your maternity leave might work for you :)
Good luck and congratulations!!
