Re: how much milk at 18 months of age?
Kids don't really need cow's milk, so the rule of thumb is 16-24oz MAXIMUM per day, with no real minimum, so long as you know they're eating plenty of vegetables for their calcium and getting vit d from sun exposure. That being said, my son has multiple food allergies so, in lieu of milk he's on hemp milk. Its unfortified, meaning we have to get calcium and vit d from other sources, but he's on the hemp milk for the healthy fats it contains. He needs all the fat he can get, he's such a scrawny little thing.
