We drink alternative milk in our house as we prefer the taste. The kids drink oat, almond and soya milk when at home and don't know any different.
When we are at MIL's house, she always offers the kids a glass of cows milk (not sure why) and she calls it "granny's milk".
AIBU to feel queasy every time she says "Who wants some of Granny's milk?" 😅(Can't find a vomit emoji)
