Hi Nikki,
I think it is almost impossible to not get any white on the yolk (maybe I am just not very good at separating :lol: ). I just let the eggs "drain" a bit before I put the yolks in a separate bowl. I use an egg separator to do it. So far, James hasn't had any reaction to this and I think the very small amount that would be still there would not do too much harm.
Don't know if this eases your mind your not, but I guess there is only one way to find out. If you are not comfortable to do it, maybe leave it for awhile, otherwise I just mixed it with formula and microwaved the mixture for about 20-30 sec and made the eggs nice and creamy. Just make sure the eggs are definitely cooked before giving it to your lo.
Hope this helps
