I gave milk cold and in a cup. I used those Nuby ones that have a silicone spout so DS could still suck on it a little. We used cow's milk, not goat, so no help there I'm afraid. I would try offering it cold before warming it up, and just start with one feed at first. If he takes that one well, he can go to another. I think I only gave DS about 6 oz., but he was weaned by this age too, so he was only getting 3 milk feeds a day. You could probably try offering a little less if he's getting 5 feeds. Hope that helps!
