Have been BFing DS since birth with no issues. He's 7 weeks now and I've developed a really sore, cracked nipple on my left side. I've been to see a HV who specialises in breastfeeding to observe a feed and she told me it's nothing to do with his latch as it looks fine and prescribed me some Jelonet gauze to put on after every feed. Has anyone used this and got success stories? When he latches on it's agonizing and I'm almost in tears at every feed.
