Any ideas what it is or how I can get it to stop? DS 2 weeks old but have only been bf for a few days (he's been in hospital and wasn't allowed food). Before I started feeding him I was expressing 6/7 times a day. It doesn't happen every time I feed but it does seem to be getting more frequent. His latch is okay, although painful at first (the expressing really started to hurt) and I can't find any noticeable lumps or bumps.
Thank you for any light that could be shed!
