Quoting ♫ boobook ♫:" Milk protein is not the same as lactose intollerance. Milk protein allergy is an allergy to milk. She ... [snip!] ... Which still has milk protein in it. So the answer would be no. I think you didn't read her whole post. Maybe the first line?"
LOL i actually did read her whole post, but it was a quick skim read while my toddler was getting into the pantry haha!! (which would be why i focused on the first sentence while i quickly read the rest)
And yes, i do know that a milk protein allergy isn't the same as a lactose intolerance, both of my boys have had gut issues (i saw a gastroenterologist today for my newborns milk protein allergy/reflux and my eldest was lactose intolerant with reflux - both had colic)
OP, as for your question RE: breast milk & milk protein allergies passing through to bub..I honestly have no clue since i've not BF'd this time.. you may be best checking with your DR
If you think your bub is more settled when you don't eat certain things then stick to what you know.
