Thanks everyone, great suggestions I will try some different cups. At the moment she has a basic sippy cup and also a beaker with a spout, but will try the doidy cup/open cup again to see if that helps. She seems to quite like dilute sugar-free squash and will drink a half-decent amount of that. Will also try some fresh juice - do you make your own Hedgehog? Would ultimately prefer that she drinks water really but I guess it comes down to limiting sugar as much as possible but making sure she drinks a good amount.
