I got a pj limerick breast pump. I used to have a medela pump in style and i must say i am liking the Limerick more. My right nippe is inverted to some degree and after pumping it comes out all the way for a while which is nice. I like the collapsing motion of the horn. It makes me feel like i can pump more often with it. If there is any friction it must be very little. I am aiming for 15a minute sessions with2hr rest. If the pump can also stimulate some prolactin then i am happy too since prolactin can help some with breast growth. Prolactin can alsoalso lower fsh and lh andand reduce testosterone production. The biggest thing is helping my inverted nipple. If i can lactate some, before i only had dropplets, then i am happy for that too. There is domperidome but the heart related warning that is newly added does not give me confidence. I might try herbs though.
