Breastfeeding.

Hi Ladies, those of you who have breastfed their babies while working or going to school. I currently have a 1 month old and i go back to college in 2 weeks, I will be storing breastmilk but my question is how do you guys manage to be comfortable during the day without having your baby latch on for long periods of time. He currently eats every 1 to 2 hours and every time my breasts enlarge and it feels so uncomfortable. Do you guys carry a manual pump with you? I will be attending college for 8-9 hours.
