Breastfeeding and pumping....

I plan on breastfeeding if possible but I'll also be going back to school before baby is even a month old. Has anyone successfully breastfed at home, then been able to have someone else feed baby while you were gone? My mom will be watching him while I'm in class and I need to be able to pump for her to feed him. We took a birthing class and the nurse said to be careful because once baby takes a nipple from a bottle they may shy away from boob, or vice versa (not take a bottle.)

I also want my hubby to be able to feed him from a bottle when I'm not around. Is this possible? Thanks, all. FTM here.
