When my son turned one, I gave him milk (formula) three times (when he first woke, before bed and in the afternoon) for a total of 22-23 oz a day. He usually is able to finish it all, but if not, then he would just leave 1-2 oz per meal. But I have cut that down now (he is 17 months now) to a first thing in the morning and last thing before bed bottle and he drinks 17 oz a day. Usually he is able to drink it all, but sometimes leaves 1-2 oz per meal. My son really loves milk (formula though, not fresh milk). I would think if he didn't like it, I would just give him more yogurt or cheese to make up the dairy element of his diet.
