Help, I'm so sore right now just the thought of feeding my little man has me cringing & crying . Apparently I'm having trouble as he has an undershot jaw. I need to do something about it asap but so far everyone just keeps saying is he's not attaching properly!!!!

So was wondering if nipple shields would help until I can get this sorted out? I know nothing about them though. If I send DF to the local baby shop, I'm still in hospital, should they be able to tell him what I need?
