Are you going to nurse out the door? If so that should be fine. I would also probably have to nurse right when I walked in the door or pump the car ride home. If you feel comfortable skipping one pumping/nursing session is nbd.
At that stage I would have had to pump for relief. DS still ate every hour and a half to two hours then so I would have been pretty full. Do you have a manual pump you could take just in case?
I would nurse or pump right before you leave or in the car for your own comfort. I can go 10+ hours at night but I'm usually getting dizzy at 5 hours during the day (and I'm 9mpp)
No. We went to a concert at 8 weeks and were gone much much longer. I would plan to nurse/pump before and right after to keep you comfortable. Supply will be fine, but super full boobs hurt. Wear pads too.
