I can't really take the idea seriously that hobbits are the children of Yavanna. For one thing, she already has children - the ents - and for another, her ents are very different from hobbits; they clearly fulfill different purposes. Yavanna is not quaint and nice, she does not want order and control. She even hates the idea that any race has dominion over her trees and plants and animals. She specifically wants the ents so they can defend and fight, her nature seems way more violent then hobbits are. I feel making the hobbits her children underestimates Yavannna's temper.
So while I respect people believing that theory, it doesn't really work for me.
