These things are SERIOUSLY amazing. They are the silicone milk suction bulbs. Got them for 10$ for two. I use them to collect milk when I am out and about. It's better than dragging my pump with batteries/plug etc. Easier to use at work too.
@eaj8290 @shorty02 i put on nipple, then squeeze it, I squeeze it more if it needs more suction. They stay really well. And are great for releasing that pressure from milk. I can fill them in a few mins, pour milk into a bottle for my daughter then if I need more, I do it again. It's worth it x1000
