My sister is a midwife, mother of two children and breastfed both times with Medela nipple shield for flat warts each about half a year. For the same problems I was offered after birth of my child also Medela nipple shield. My little one is now almost 3 months old and so is drinking very well. Try not folded without particularly, so I've now given up without a guilty conscience. I probably would also hammer out with a lactation consultant breastfeeding without, but I find it consistently advantageous to breastfeed so. Sure, you just have to each use, it should at least initially sterilize 1x daily (which is no problem; finally, pacifiers have indeed in the Steri), and if you are traveling, you have a with you. There are but a small box that can prima clean also. My child gets healthy breast milk and is thanks to the recess on the cap with the nose directly at the chest. I may be a disturbed milk ejection not complain; there is plenty of milk, and the baby is thriving. Especially since you have no problems with sore nipples and ev. Infections. If necessary, too much swallowed air is pushed open and does not lead the same as is often claimed to bloating. I would not hesitate to re-use this nipple shield, which can be used immediately without any preparation of the breast. However, if in spite of flat or inverted nipples without hidden want, should be prepared as early as pregnancy with Brustwarzenformern it. For me personally it was too annoying. My tip: choose when not too big nipples size S!
