I thought it was because of the passage of time since he was born plus the evidence from this graph of my total daily pumping time:
I should have been suspicious that the drop was too much to be explained by just the pumping time because after an initial drop, the number of times I have pumped a day has stayed pretty even:
Today I finally figured out what is going on. I use two pumps: a Medela Symphony at the house and a pump in style at the office. The pump in style seems to have reached it's last leg. I had thought this a few times in the last months, but I convinced myself I was crazy. Today it was obvious that it just ain't cutting it. Pumped twice so far today and under 50 mL total each time. And after the second time I experimented with hand expressing. With a good pump with the Symphony, I can then remove maybe 5 mL per breast. I got over 30 mL from each breast working less than three minutes per side.
I think I should have been suspicious based on the change in the ratio between the two sides (this is right divided by left):
- Do I cart the symphony back and forth? This is one I bought myself, so it doesn't have a hard case, so I worry about damage to it. Also it would be huge, I really don't want to do that.
- Do I try just pumping once or twice during the work day and running home?
- Do I rent a second symphony and leave it here?
- Do I just buy a new pump in style as it's handy... Also, I have a trip to Canada coming up that I was considering taking the pump in style instead of the symphony just due to size anyway.
- Do I declare myself done/incompetent and just quit?
I'm leaning towards just buying another pump in style. If I remember right, that's around $300? I feel like I've tried everything. Replacing all the membranes has seemed to improve the performance of the Symphony, but the PIS is just getting worse and worse.
I went home and pumped (just finished) and got more than double what I had gotten from the two pumps I had done at work today!
For the sake of visual completeness, here's total broken down by left and right to make the problem a bit more obvious (yes, I know I should make more useful graphics given the data, but these are fast to autogenerate):
I really do need to take some sort of action, like today. Thoughts?
