People always wanted to hold the baby - or take her and "give me a break" while she was trying to nap (um, I need a break when the kids are NOT napping!). I had a cloak I used as a nursing cover - it was so big, no one could tell if baby was sleeping or nursing. She got a lot of naps that way, I got a lot of snuggle time.
Crossword puzzles and books. I could nurse sitting cross-legged on my bed baby in my lap on her boppy, with a pillow in front of me with my book or crossword puzzle propped on it. Got a lot of reading done.
I'm with Tracy on the efficiency. My diaper bag had a change of clothes, two diapers, and a pack of wipes. If I even carried a diaper bag - sometimes, the diapers and wipes just got tossed in my purse.
