Hi,
I have been giving DD pancakes AND waffles. I made the pancakes with the yolk only first but now when I make waffles and pancakes for us she gets some and LOVES them. I have some I made frozen to take out with me as snacks. I think cooking and baking with eggs greatly reduces the risk of egg whites as they are small in amount and baked therefore fully cooked.
If you are pretty vigilent about no egg whites period, I would wait until 12 months and the OK from your Dr..
