My son had a bad night last night after I gave him some margarine made with soybean oil. I do not know if it was just a coincidence or not. Has anyone else had problems with their MSPI toddler and margarine? The margarine has no diary in it. It is called Nucoa.
Soybean oil is a fat and not a protein, so in general most MSPI babies are fine with it. I read an article once though that questioned this because it said there actually are traces of soy proteins in soy fats. My guess is that it was a coincidence but it’s always a possibility.
