I have tried on numerous occasions to put my baby straight onto the breast but my nipples always end up killing me to the point of tears. The last time i tried, it was ok for two days (a little sore but bearable) but ended up killing (naturally a build up of the two days). I have used nipple shields (very messy) since hospital and my breasts and nipples became very sore there. My question is, what's the big deal with using them for the whole time i choose to breastfeed? The only thing i can think of is nipple confusion and the fact that he takes in lots of air whilst feeding. I have already tried a lactation clinic and it didn't work. Some thoughts or advice would be appreciated.
