You will definately want to do your research as to what you decide to introduce.... if you are still breastfeeding, I would continue to do so, especially through the upcoming winter/flu season - particularly with the swine flu issues...in fact age 1 is a very 'old fashioned' number as to when to switch from the breast (human milk) to cows milk as the WHO- World Health Organization - recommends sticking with human milk until age 2.
Otherwise - don't worry or be in a rush to introduce cows milk at all....after your research if you feel comfy with giving glasses of milk, then do so, but honestly it is not necessary, so there is no rush. The main reason most people want to feed cows milk is to get their daily calcium, but you can provide that is many, many other ways, so I'm just saying that you don't need to worry about switching or feeding it right away, or at all for that matter :-)
Almond milk and/or rice milk are awesome healthy alternatives....I would stay away from soy products. There is plenty of research results available on soy as well that would be worth reading if you start considering it.
Anyway - organic means more than having hormones added or not, it pertains to the number of chemicals, pesticides, antibiotics etc that can be present, used, or fed to animals or to grow food items. Sure, we are alive and our parents may have fed us whatever, but that is a poor stance to take based on changing times, new technology and the development of new chemicals, etc....times are different than they were for our parents or us. Look how many diseases and problems there are today? They didn't just come from nowhere, they are the result of our exposure and our consumptions....definately do your research.
I don't think I personally can put a price on my kids exposure to chemicals and pesticides....sure, regular products may be cheaper, but you pay for what you get and we cut spending in other areas of our lives to cover the difference.... I definately think the benefits of eating organic and the safety outweigh the risks of not....

Also check out the Environmental Working Group website for pesticide content in various fruits/veggies....it will let you know which are best to buy organic and which are probably ok to buy conventional
