Return to work plans (pumping)

Br

I’m trying to reach the teacher mamas out there. I’m currently trying to come up with a plan for pumping once the new school year starts up this fall. I teach high school and am the only teacher for my department. I know that any breast milk I can give baby is great, but I’m worried about my supply taking a nosedive upon returning to work and I’d like to go as long as I can without supplementing formula. (I’m not against using formula if needed, but if I can keep breastfeeding or at least pumping I’d like to.)

So my questions are: What are your plans? How willing has your administration been to work with you? How easy or difficult has it been to find a place and or time to pump? Do you have any advice for other mamas who teach?
