Hey now! It is difficult to work with kids but I've done it- twice! With my first I went back to my swim team, with my second we went back to the office after a week. Did I love it? No. But did I feel like I needed to? Yes. And it worked out just fine.
Here's what I do with a new baby at work- the sling!!
I have a good ole Maya ring sling that I love. It can kind of swallow a newborn, though. Baby #1 liked to be lying down, baby #2 likes the newborn front carry (facing you). Teach them the sling when you aren't working, so you aren't trying to do it WHILE you try to work.
I also rocked a cradle by my computer with my foot, for doing my swim club paperwork while I was at home. Worked!
Use your partner- I would have dh take the baby for an hour after dinner and squeeze in a little more paperwork.
With this baby, I returned to an office where they were happy to have me; even with the boy! He was a fussy baby, so I wore him a lot and just planned on taking a lot of breaks. It takes twice as long to get the work done, but it gets done!
I also use a pack n play for baby to have a safe place to sleep. But at a few weeks, mine didn't like to be set down! So the sling or try a baby bjorn. Walk/pat/jiggle baby to sleep and go back to work.
Good luck! Meg
PS: My kids like a pacifier and I will say that it helps a lot when you are working. I know that if my attention was just on them 24/7 I wouldn't use a paci as much- maybe at all. But when you need your kids to be patient (and they'll take it) a paci is nice. Although no paci for the first month- 6 weeks though; you want breastfeeding to be well established.
