I'm having a weird few days of pumping and I need some insight. I pumped in the evenings all weekend and was getting about 4 oz. no issues. I pumped today and yesterday and never got more than 2.5 oz a session. I've replaced the membranes, I put a new filter and tubes on a few weeks ago. What else could it be? I just can't believe it's me as I pumped at the same time Sunday night as Monday evening and got half the amount. I feel like there's good suction. LO is almost 8 months, nursing the same amount he normally does. He is having the same amount if solids. I was counting calories a bit but stopped when I had a supply dip a few weeks ago. Help me figure this out!
