We’ve been cutting out dairy in our house to help my wife with breastfeeding, as dairy protein carries into breastmilk and our son is sensitive to it (supposedly i was too as a baby). It’s been an interesting experiment to say the least. I’ve found so far that some variety is needed with the milk substitutes as none of them really seem to be a direct replacement, but rather have strengths and weaknesses with different applications that one would normally use milk for.
