Have you tried raw goat milk? I wouldn’t recommend pasteurized milk of any kind since all of the enzymes for digestion are destroyed in that heating process. Goat does taste noticeably different than cow, but it’s naturally lactose free. I used to drink almond and oat milk, but I despise both now that I’ve learned about raw milk.
Scratch that recommendation. I decided to do a search on the legality of raw milk in Norway. Looks like it’s illegal 😫 I’m sure it’s still possible to get, but definitely not easy. Here in the USA some states are legal and some aren’t. Where I live you have to have these things called herd shares (aka partial ownership of the animal), which are very annoying to setup. I’d much rather just go to the store and be able to buy what I like with no government stopping me.
Sounds like you have amazing parents. We are both lucky in that regard.
