I never wrote down my head cannons, did I? .3.
Norway loves children
I believe he raised all three Iceland, Greenland and Faroe Islands together by himself when they were only babies/young toddlers before he was put into a union with Denmark and Sweden. When Denmark was forced to surrender Norway over to Sweden during/after the Battle Of Copenhagen, it left Norway heart broken to learn the three were to be remained under the Danish crown rather then coming with him. He shows more expression around children than he every did with any one else.
Norway has a soft spot for cute things and animals.
Another thing I believe is Norge owns tons of stuffed animals and anything cute he can get his hands on, which he commonly hides from the other Nordics. He also loves animals, to the point where he picks up strays or sickly animals off of the streets and gives them new homes, sometimes to the point of trying to heal their illness with his magic instead of bringing them to a vet.
I've a load more .3. That I miiiggghhtt post. These are just my two Norway ones.
