I'm sure I've shared this before, but in other countries (particularly in Asia) soft steamed egg (the whole thing) is a very popular first baby food. I didn't give eggs to Dora for the first year because of my ped's rec. For Arwyn I fed her fried rice around 7 months from the food court before I realized there was egg in it. Laurel I fed steamed egg a couple weeks ago, and today she had a waffle with egg whites in it. She's fine
If your family has a history of food allergies I would of course be very cautious, but otherwise I really don't see the point (anymore) of waiting such long periods. I mean, if a kid is going to be allergic, does it really matter when the food is given? At least, according to the newest research, that seems to be my impression.
