Baby not interested in milk

Kim

OK so I know it's a little early but thats not the question here. My son is almost a year old and i been trying to wean him off formula like I did with my oldest. I mix the formula with milk. My oldest was fine after like a week but my youngest just don't seem interested in milk. Sometimes he won't drink the whole bottle if I put milk in it. Or I will just give him a couple oz with meals and he won't drink it. He drank like 4 last night but when I tried this morning he didn't seem interested. Like I said my oldest was OK with it. Is that normal?
