Hi jaqui, I had terribly cracked nipples first time round and have a huge scar on one nipple to show for it!! Unfortunately same thing has happened second time round, cracked and bleeding again and low and behold another scar!! The things we do for our kids aye!!
Sorry to not be able to offer any advice other than just keep getting your latch checked by the hospital staff and your midwife until you are happy.
Everyone kept telling me it was a good latch but I knew deep down something wasn't right but no one seemed to be able to understand what I meant until I went to the plunket family centre. Eleven weeks on I am still not convinced we have it right yet!! So keep asking and asking until someone helps you!!
Hope the rest of your pregnancy goes well! All the best
