My nearly 18 month old daughter had yogurt (plain, balkan style) with fruit or fruit puree mixed in from around 9 months and shredded cheese before that. She won't drink cow's milk at all so I can't help there. My daughter will eat yogurt with her fingers or a spoon, and yes, it is VERY messy! (but fun for her).
While organic is great, it is good to know that Canadian milk does not contain hormones or antibiotics as this is much more strictly controlled than in the US. If you are reading US info, keep this is mind as the regulations here and there are different.
