I do unlimited. It *can* cause low iron but I feed a well rounded iron rich diet and we have no issues. I'm a dairy farmer and it's insane to me to limit milk lol our peds have never had a problem with it
I offer about 5 oz 2-3x a day
No plain cows milk but we do a smoothie once or twice a day
It’s recommended not to give over 24 ounces a day! I give mine 5-6 ounces 3 times a day!
