Is it because cows' milk is cheaper? Or is there some other reason?
I'm interested because we are currently living in India where it wil be difficult to be sure of the purity (growth hormones etc) of cows' milk -- we will still be here when my nine-month-old baby turns one; will he suffer if I give him formula instead? The water we dilute it with is another issue, but he drinks gallons of it in the heat anyway!
Thanks for any ideas ...
