1 year old won't drink cows milk- should I be worried?

[MinisterforCheekyFuckery]

DS is 1yo and although he's happy to have cows milk on his Weetabix in the morning, he won't drink it from an open cup or a sippy cup. He has a yoghurt, a portion of cheese and milk on cereal every day so how much do I need to worry?
He was formula fed and until recently was having one bottle in the morning and one at bedtime but we've knocked the morning one on the head and now he's just having the bedtime one. I'd like to stop the bedtime one too as I don't feel he needs it (he's a good eater and has three meals a day plus one or two snacks) and I know it's not good for their teeth. But that means he won't be drinking any milk, just water.
I mentioned it to the HV and she just said keep offering him the cups of milk and he'll get used to it eventually but surely that's not guaranteed? There must be kids who just don't like the taste.

DD stopped drinking milk when we moved her away from bottles. She loved her milk / bottles and they were a fixed part of her routine, so we thought initially that it was just a case of stubbornness, and a matter of persevering, offering her milk but not in a bottle. That she would eventually accept that there would be no more bottles and take the milk from a cup.
But she never did. She's five now and has never drunk milk since that last bottle when she was 12 months.

She'll have milk on cereal, she'll have yoghurt and occasionally cheese. But no milk as a drink.

Incidentally, she used to be very consistently and predictably car-sick. If she had had milk within about 3h before going in the car, she would throw up if we went further than 15 minutes, every single time.
Since she stopped drinking milk, she hasn't been sick in the car once. Make of that what you will... I'm thinking perhaps the milk didn't really agree with her, and she didn't really like it, but it was just the comfort of the bottle / the suckling that she enjoyed.

DC was like this when we weaned from formula, he doesn't like milk at night and only in his beaker in the morning. He also refused it for weeks, even in bottle.

So I use to put it in cheese sauces, weetabix, scrambled egg ect and still offer it in the am. I actually caught on that he likes his milk slightly warmed up like formula so we still do that every am (he's 2 now). But as long as he's having cheese and yoghurt for now hell be fine.

Honestly you could ask 10 health visitors the same question and get 10 different answers

I have never understood why humans routinely stop feeding babies human milk and then start feeding them milk from an entirely different species.

It doesn't make any evolutionary sense. That is why so many people are intolerant to it, we just didn't evolve to drink cows milk.

I wouldn't worry. My 12 month old DS doesn't really like milk - we still offer but have stopped stressing about it as he is growing fine. TBH even formula has always been a struggle ever since we started weaning him he quite often flatly refuses it even when hungry. I hate milk and always have so understand his pain! Never been tested but I think he has a bit of intolerance.

DS1 on the other hand is 3.5 and still loves cows milk as his drink of choice! He still has a cup on walking, on his cereal and at bedtime! Personal preference I guess!!
