Baileywick

Baileywick is the Castle Steward, his responsibility to make sure everything in the castle is where it should be when it should be, as he explains to Sofia on her first day as a princess.

Personaly
He is very dutiful and a bit of a stiff, but he's nice and patient. He has also given advice and guidance to Sofia, not just because it's his job but also because he is kind and fond of the new princess.

Such was when Sofia took the blame for ruining a stained-glass window, Baileywick correctly suspected it had actually been Prince James, and gently scolded Sofia that telling a lie to prevent someone from getting in trouble is still wrong.

Recently, Baileywick has shown himself to be uncommonly selfless and quite dedicated to his job as the Castle Steward, shown in the episode Baileywick's Day Off, when he didn't want much on his birthday and had to practically be shoved out the door for him to go and spend his day off/birthday with his older brother Nigel.

Despite this, he willingly put the needs of James, Amber, and Sofia before his own birthday, and almost didn't get to spend his day off ith his brother. Luckily, the children and their parents, King Roland and Queen Miranda, salavged what time was left to give him a proper celebration.
