After about 5/6 days of breastfeeding well (apart from some pain), my nipples became very sore & cut - there was a lot of blood so I was advised to use nipple shields for a few days until this healed and also to allow the engorgement to calm down. DD took to shields really well which i was pleased about and she fed great! However, after few days i started to try and go back to normal - sometimes she fed okay, but mostly she was eventually latch on (after a lot of encouragement) and then after a few sucks keep slipping off again. She seems to have changed her latching on technique to suit the shields. For convenience I would love to ditch the shields - but I also want to ensure DD is feeding enough and currenly she seems to be doing this better with the shields. Any advice please?
