Bä bä, vita lamm har du någon ull?

Just FY, killing is the name of a baby goat.

Edit: as it states “the swedish word for kid is killing” which is ambiguous IMO because the swedish word for kid is barn!

Kid is the name for baby goat in English, so context clues are enough here to know it’s not talking about a human child
But the kid does live in the barn with the other goats. Unless it's a human child type kid. Then it's less obvious if it lives in the barn or in a house next to it.
Much clearer now thank you
