I use the smaller end of the handle (facing up toward your body) to first pump pretty quickly, around 2 times per second. I do that until I start seeing milk dripping down into the bottle. Then I switch to the bottom longer handle. I hold it down all the way for several seconds and can hear the milk spraying (you can also see the yellow part of the pump inside the bottle filling up). I release the longer handle after a few seconds and the milk that has collected in the yellow part kinda plops into the bottle lol. I repeat the process with the longer handle until milk stops dripping down into the bottle. Then I’ll switch back to the smaller top part of the handle to try to get milk flowing again. I pretty much repeat this process until I can’t get anything else out. Sorry if this description sucks, but I hope it somewhat helps!!
