Are we allowed to take the small ready-made cartons of formula through in hand luggage? We've got an early morning flight and don't think breakfast is an option at 3am so want to take some milke for DD until its time for proper food. We're flying from Bristol and I doubt whether they'll have any stocked airside. Alternative option I suppose is to take some of the small sachets of formula powder and get water once we've gone through into departures. Would this be allowed?
