I unfortunately discovered recently that I have high lipase. My frozen stash is all sour. My son is 9 months old and I am currently working 3 days per week. I am having a hard time keeping up with the milk requirements. I am at work from 830 - 230, I pump once at 12 and usually get 4-5 ounces. I also have started pumping in the morning and at night after he goes to bed and only get about an ounce per session. I am worried I wont have enough milk for him being that I cannot use my freezer stash. Can you recommend ways to increase my pumping output?
