I've got the manual breast pump but no instructions and although I can assemble it into something that seems to work like a pump, I'm not convinced I've put it together properly.
The main thing that baffles me is the little white valve thing thats shaped like disk with a star on it. I don't know which way up the star pattern goes - do I slot it in from the bottom with star facing up, or slot it in from the top with star facing down?
Either way, nothing seems to happen when I use the pump either way!
any assistance appreciated!
