14mo DD has always struggled to get a good latch on my left boob, my nipple is quite flat and we've had a bit of a battle to make it this far. I thought we were sorted fir a while though.
Recently (possibly because she's too long for me to hold comfortably tummy to tummy) it feels like she's shredding my nipple during some feeds.
It isn't unbearable but we had an episode a few months ago where she had one lazy feed in the night and she wore a hole in my boob with her new tooth
so I'm a little paranoid about that happening again!
The thing is, I can't get anyone to check her latch because there is no way she'll feed with anybody in the room, she's too nosy easily distracted.
I really want to feed her until she self weans, but it would be nice to be comfortable while I'm doing it!
I don't know what advice I want really, maybe just to get it all down so I can try to figure it out myself! 
If you made it to the end then thanks for reading
