I do not know what I would do without this nipple shields, probably not more silent ... My daughter slept after birth ONLY, characterized it was generally very difficult to encourage them to breastfeed. My nipples she hardly believed and gave me as a sister of one of these cones, and I must say this was the solution, I use them for two months and still recommend them only, especially the nipples remain so well preserved and they are not irritated. For the price I bought the same 2 packs of two, as from time to time a little hat is gone (I'm a little Döspaddel) However, I would slowly try of the hat to get away, because they have thereby always and everywhere need and also a way to make them clean. But this should not succeed so I use them until weaning. My midwife recommended me generally Mendela brand, whether breast pump, hats etc.
