Giving cow milk??


I don't give my baby cow milk he about to be 8 months next friday and I see his doctor Monday so I am going to ask but I've been reading a lot that parents have started their 8month-11 month old into cows milk and then getting rid of formula all together before the baby is 1 years old so young I've heard good things and hardly any bad or negative things or course I am consulting my doctor because I am just curious myself but what do you other mommies think about giving 8-11 month old baby cows mom instead of formula/breast milk
