I'm returning to work in two weeks and I won't be able to pump for 8 hours. I'm starting a new job and my day is so busy, it's not an option right now. My LO is 8 months old and has been exclusively breastfed so I'm really trying to maintain my supply by pumping every 4 hours At night, pumping on my way to work, and ok my way home. Thankfully he's been sleeping through the night. Will I lose my supply if I go 8 hours without pumping? My breasts can hold about 8-10 ounces max when they are super engorged.
