My grandson (20) up until 2 days ago loved his milk in the morning and evening (from his bottle as he won't drink it from a cup). All of a sudden he's stopped drinking it. He just holds it in his mouth but won't drink. He's not ill and there's nothing wrong with his mouth. He's eating ok and drinking water. The milk wasn't off or anything and teats are fine (Cow's milk by the way). He is a fussy eater (sensory issues and being monitored for his different ways) so there aren't a lot of things we can get down him for calcium. He won't eat yoghurt or cereal anymore (hasn't done for a while), he's fussy about fruit and veg aswell. Does love cheese though. Any suggestions on why he has stopped and how else to make up for the calcium he won't be getting? We'll keep trying of course and are trying different cups.
