15 month old DS will drink juiced from his beaker happily all day long. He also loves his milk but put the two together and he screams. HV has advised me to start putting his morning milk in a beaker but he will not touch it. I've tried leaving him with it the way I do with his juice thinking he'll drink it when he's thirsty but he just screams at it. If I decant it into a bottle he guzzles it as usual. He's a really easy going baby so this is not like him at all. Does anyone have any ideas how I can get him to take it from a beaker?
