How much milk & juice should a 1yr.old have?

I always heard/read less than 4 oz juice a day (here we do juice half and half with water two times a day to equal about 4/6 oz juice) and between 16 - 24 oz milk. You do need to introduce an open up.............we use one at meal times. They just don't want your son dragging around a sippy cup with juice or milk in it all day long. Maybe they meant at least 15 oz of milk a day or that that is what you would get on WIC (enough for 15 oz a day and anymore you have to buy yourself).
