With the Medela nipple shield in the largest size I have breastfed from birth, as the nipples were too small and the baby had trouble sucking. And it worked very well. Unfortunately, we have so far can not get used to breastfeeding "without" and actually it fits so well. (We pump alongside eh much with the breast pump off - no problem at all - contrary to common information in literature and in technical discussions). Meanwhile - as it is quite Verschleissartikel, which must be washed permanently, somewhere will love, I have also tested nipple shield other companies. The best part was the nipple shield of Mam (price / performance / quality), it is even less on the breast on, which allows a more beautiful "feeling" of closeness and skin; followed by Medela, and only then the Philips (which was to me "dick" - is perhaps helpful in actually sore nipples helpful, but for "real feel" drinking significantly too thick compared with the other 2 companies). In all 3 tested nipple shield 2 Pieces in the Pack were always included. With Medela me the yellow box attached like it very much.
