Any other working moms out there?

Jess • Married to the love of my life, totally smitten with our little girl and boy.
Anyone else work outside the home? I started back three weeks ago and would love some other moms to chat with who understand what I'm going through. I'm surprised there isn't already a working moms group on here, or did I somehow miss it?
Anyway, I'm a first time mom to an almost four month old little girl. I work in NYC and commute in from NJ. I'm also breastfeeding my daughter so I have three breaks a day to pump which actually is much more enjoyable than I expected. It's nice to have three times a day when I get to just relax and be a mommy and focus on my baby girl. 
Anyone else planning to go back to the office or already back?
