Kathy, You make me realise that I never questioned this and have always taken it as one of those things ''everyone knows''. No, I never tested and never read any research on it, just presumed it to be true. I think it may even stem from my childhood where I learned from my mother or even grandmother to always do the milky things with cold first and hot afterwards.
Warmly,
Gonneke, IBCLC, LLLL, learning in southern Netherlands
