Ok, so nipple shields sounds definitely out!
Did you find Kyle fed less during that time Cuppatea, and does he only bite now when it's a tooth coming through?
That's good to hear that it only lasted a few days each time, I really hope it is the same here. This is the 4th day so fingers crossed.
6 teeth....eeek. I can't imagine the pain when there's top and bottom teeth to bite with
