i left melissa with my parents last nite and left 3 cartons of sma, 2 (i think) cartons of aptimil, and one carton of cow&gate. the reason i left different ones is in case she doesnt like a particular brand, or it makes her sick or something, if shes got others she wont be going without. today when my parents brought her home there was one carton of sma and the cow&gate one left. so i worked out millie mustve had the sma and the aptimil. i suddenly realised, i think i remember reading that changing milk can upset babies? does it matter if she has different milks in the same day (or nite)?
