my son started to take cow milk when he was 15 months, since i couldn't get the beanstalk milk powder from bonjour. he is now 17 months.
he takes dairy farm "smart milk" contains DHA and "healthy milk" contains various vitamins.
he likes cow milk very very much. he took around 30 oz beanstalk per day before and now he can finish 40 oz cow milk aday.
his skin texture is better than before, very smooth and white.
Yes, most kids in US drink cow's milk after 1-yr-old unless they have serious allergic reactions.
Most doctors here said that drinking formula after 1-yr-old will make the babies not feeling hungry thus not eating much solid food.
