For yogurt we do either Stonyfield Farm Whole Milk Plain (organic) or sometimes for a treat the French Vanilla. (I avoid YoBaby as it is loaded with sugar.) Or if the budget is tight that week we'll do Dannon Natural Whole Milk Plain (not organic but does not contain anything except milk - no sugar or additives)
For cheese we just get whatever's on sale. I'd love to do organic but our grocery budget is about $90 per week and organic milk here in our city is twice as much as regular. I hate thinking of the hormones, antibiotics, etc but I have to balance that against her (and me being pregnant) getting enough veggies, variety, etc.
