I do not.
I kind of stopped leaving during pregnancy... unless I was reallly craving something. And then worked the last five weeks from home.
Once i came back to work, I was pumping all the time, so I always ate lunch at my desk.
Now it's bitter cold and I like eating at my desk. because I've turned into a social hermit.
I work 9-5ish so it all evens out by week's end.
