After all this time, I still have a question about EN equipment! :ywow:
We've always used 'bags' to hold the formula with the tube attached that runs through the pump. But, my recent supply of 'bags' are not bags; they are hard plastic bottles with openings at the top and bottom. You remove the cover at the bottom and attach the tube. So far, so good...
But, do I remove the top cover when I run the pump? With the bag, as the formula was pulled out, the bag deflated; but, with a hard plastic bottle, won't I get a flow error? At some point, the pump won't be able to pull out anymore formula as the 'inflexible' bottle won't accommodate the reduction of fluid without allowing air to go in. Am I making sense to anyone who has used these EN pumps, etc.?
Not the end of the world if we can't finish the formula tonight but... would rather not miss a night if we don't have to...
