[Elf] Why was Buddy not given a human-sized bed, desk, and other furniture?

They're all expert craftsmen, and his clothes are custom built for him. Santa also has extra-large furniture built for him. Buddy has to sleep on two beds wedged together in a room with too low a ceiling. After all those years nobody thought to give him bigger things? It's obvious he always knew he was bigger, making his things bigger would have been of no issue to them and wouldn't have clued him in to his human origins.

Maybe the Elves and Santa just never thought of it. They're obviously caring individuals and collectively selfless; so some theories:

Buddy's life is fleeting to the Elves. They are hundreds (perhaps thousands) of years old and just plain didn't notice how fast Buddy grew up. Couple this with the fact that their entire focus is on getting ready for Christmas it easy to imagine that it just simply slipped their notice.

Darker: They don't think it's worth the time distracting from their work because Buddy will be dead in a relatively short amount of time.
