I don't understand - are you supposed to FEED her eggs to get her ready for the injection? I never heard of that. Or is it just that this will be her introduction to whole egg? If you are supposed to try her with an egg to see if she reacts, I would think that 3 days before the jabs would be plenty of time to see if she is allergic, and close enough to the 1 year mark to make no difference developmentally. We started dd on whole eggs the same week she turned 1, I can't imagine a few days one way or the other would make any difference, it's not like something magic happens exactly on the birthday.
