R.D.
I went back to work when my 2nd was 3 weeks old. I always pumped in my car on my break (it was night time, so it was dark), listened to the radio, caught up on school work, ate my dinner... all while pumping. Every so often someone would pull up and park besides me and they never failed to do a double take like 'is her boob really out?!' followed by the super embarrassed 'oh sh!t it is! Act like you didn't notice!!' look ;)
