is this true?

my friend had the ordasity to tell me that I need to give my 11 months old cow's milk and at least 3 bottles worth a day the thing that bugs me is that she doesn't have a child her self and she was telling her friend who has two kids that I wasn't doing this and she apparently told she had to. not to mention the fact that she was insistent that if I don't do this my baby will have brittle bones and break one if I'm not careful is this true? also i had said that she has yogurt and cheese but she told me this isn't enough. any advice would be great thank you
