My friend is French, his wife Portuguese, they live in England with their two children. When all together, they all speak English with each other. When the kids are with one parent, the speak that language. In the park with father, French. Baking with mother, Portuguese. Bedtime stories are in the language of the parent reading. Kids switch between languages easily and understand what to speak with whom. Effortless trilingual.

Another friend moved country with her husband and had three kids. Home language was always mother tongue, both my friends had fairly bad English. Everything outside parents is in English for the kids - media, school, anyone outside the household. Again, the switch for the kids is really easy, they are fluent and have no accent in both languages.

Why limit yourself to only tacos? Spoon a dollop of sour cream on your chilli or any hearty soup or stew, Mix it into gratin or mac’n’cheese before baking, make a salad with fresh cucumber and tomatoes, dill and/or spring onions… The world is your pot of sour cream

That absolutely applies to harder cheeses. Cheddar, provolone, parmesan all freeze and defrost with no issues. Cream cheese changes the texture and will not be that good anymore. Brie and camembert get a bit funny too.
