I'm currently on a no egg diet (we're challenging for DS's eczema) and there's a few recipes that I would like to cook (one being the lactation cookies) that require eggs. I would like to know a few things:

1) what is the egg replacement called? brands etc
2) where in the supermarket am I likely to find it?
3) would egg replacement work in the lactation cookie recipe (if anyone has an idea about it, otherwise I'll try it and see)?
