I was looking forward to trying to express the rest of my milk off this morning . Have read all the tips and was hopeful. I've tried the Avent electric pump but friend gave me the manual version and said it was gentler. Thing is I can't seem to get a good seal and any suction. Are you supposed to squeeze your boob into a pointy shape and shove it into the funnel or lean forward and press the pump in so boob is flattened or neither??! Said it was a stupid question but I didn't even get one drop :(
