So I have a bit of a dilemma.. Going abroad when LO is around 5 months I have read that you can take the ready made cartons or pervade bottles HOWEVER my LO is on aptimal anti reflux so there isn't cartons and if you pre make them up iv heard they go solid after 2 hours.. If I go out for the day I usually take flasks filled with water from the tommee tippee machine ( institutions say to add powder after at "hand hot" temp) and I don't think they will let flasks on?! Any help will be great! Thanks xx
