Hello bamboo
When my ds was 12 months old, I started to try to give him milk as a drink. He'd only been breastfed and had water up until then, but had milk on cereals, in porridge etc. I tried various different types, temperatures, beakers cups, I even tried rice milk with calcium, as it's quite sweet and light, rather like breastmilk, but everything was to no avail. I tried for a couple of months and then gave up as he just wasn't interested.
He self-weaned from bf at 18months, and at that point, I spoke to the HV and she said it wasn't a problem if he didn't drink milk, as long as he had calcium from other sources, he'd be fine. He liked yogurt, cheese, custard etc, so that was good. She also suggested sardines and broccoli as non-dairy calcium sources - and he loves broccoli! He is 7 now and in great health, still doesn't drink milk. I understand many different cultures in the world do not drink milk after weaning with no ill effects.
I'm not sure if this advice would apply to a younger baby though - you may want to check with your HV.
