Cow milk is recommended as part of the diet of young children, with government guidance noting that although calcium-enriched alternatives to cow milk (such as oat milk with added calcium) seem fine, there is as of yet insufficient data to suggest that replacing cow milk from the diet of young children won't have a negative effect. It's a fair and balanced view I suppose.
In the 70s a dairy campaign taught everyone that three pints of milk a day was healthy, but that kind of propaganda is in the past. Still, the Dutch tend to have a very positive view of our dairy industry, in part aided by animal welfare programs and certifications. That doesn't address the environmental impact of course.
I have switched to cow milk with a certified guarantee of decent treatment of the cows involved for my young son, and oat milk (Oatly usually) for us.
In time of poverty, cow was actually essential part of life. A life saver. You get milk, butter, sour cream, cheese, cottage cheese. I think not every word from this list makes sense to some living in some other countries, because not all products are consumed in other places in the world.
Also, question to people who only drink milk with coffee: Do you buy small processed pouches of milk for one cup of coffee, or do you drink enough coffee to use up a 1L (~4 "cups" in US lingo) packaging of milk before it goes bad in the fridge?
We were given glass of boiled milk every day at school, and I don't remember any kid being lactose intolerant. I didn't like it back then. I prefer cold.
When I'm eating cooked buckwheat grains, glass of milk suits me best to wash it down.
We always have milk at home, my 16 and 13 yo children drink it, or eat with muesli
One of them drinks pure milk, the other much less. I do it from time to time my wife rarely to never.
