it's been a week now that I'm pumping (baby unable to latch onto boob) and I notice that around 2-3 mins of pumping my armpits start itching. I thought maybe it was because it's been a couple of days since I shaved them but it's still happening. anyone have any recommendations on how to stop this? especially since I don't have a hands-free pump.
