won't drink cow's milk
I am still BF-ing 2 to 3 times a day, so I'm not totally worried yet, but DS fully rejects cow's milk, and I'm getting very low on frozen BM to send to daycare.
I've tried it cold, warm, whole, 2%, in a bottle, in a sippy cup, with chocolate flavor, with strawberry flavor... but, DS eats yogurt and cheese with no hesitation. He takes one sip of milk, makes a nasty face, and either hands the cup back or throws it on the floor.
Pedi isn't worried, said some kids aren't big milk drinkers - he himself wasn't and still isn't. He said if DS is thirsty enough, he'll drink it. While I trust his medical opinion, he's not burdened with the responsibility of feeding my DS well every night, like I am. 
Reassure me that DS isn't missing nutrition (he's a GREAT eater, hasn't turned away anything until we tried milk) and/or please suggest more ways to "trick" him into giving milk a chance. All my research has me going in circles. THANKS!!

I know it can be stressful but it sounds like he's getting great nutrition from his foods so I wouldn't worry about it. He may start liking it one day or maybe not. WCM is not a necessity for us humans. Yes, it is a great source for fat, Vitamin D and Calcium but it's not the only source. And if you feel like he is lacking in anything, he could always take a vitamin.
My DD hates milk also until I mixed in some Vanilla Pediasure. And she will only drink it out of those take & toss sippy cups.
It sounds like his diet is balanced enough that this isn't a big concern. I wouldn't worry too much if you have exhausted all of the options and still nothing works. I suppose you could always try again when he is older. It's hard though, especially since we are programmed to be sure our LOs get lots and lots of milk. Good luck, Mama!
DD does not drink milk. I weaned completely in July and after talking with her pedi, I just make sure to offer plenty of cheese and yogurt on top of a balanced diet. She will take a sip here and there, but not enough to really even mention. She's willing to eat cereal in milk now, but she used to refuse even that.
I know it can be frustrating, but I've run in to quite a few toddlers that just didn't like milk. Good luck!
