13 month ds off to nursery soon, ebf & good intake of solids. But...he's refusing to take any expressed, formula or cows milk in any type of cup or bottle. He'll happily have water in a sippy, doidy or nuby straw cup, but milk? Forget it. I wouldn't worry except he doesn't really eat at nursery either, so no milk & no food from 8-5? He's done half a dozen settling sessions & I've sent ebm for him which has been untouched and chucked out. I'm at my wits end, any advice or ideas? I'm hoping he'll be so hungry he'll give into food or milk eventually
