Author's Note: Because Hamish can't be well-behaved ALL the time, he's the son of Sherlock Holmes after all ;)
This was a nightmare. An absolute, undeniable nightmare. Sherlock wondered what he could have done to deserve this. Of course, there had been that incident with the rooftop and the whole suicide… thing… but surely John had gotten over that by now, hadn't he? After all, that was so 2012. And sure, there was the occasional head in the-
"Father, it's too hot!" came a little four-year-old voice, bordering on a whine.
"Hamish, by the time you quit fussing and actually get in the bath, it will be the perfect temperature," Sherlock replied, wincing slightly at how much he sounded like his mother.
The little naked boy pouted at him before turning away and sitting on the floor with his arms crossed. Sherlock sat back against the toilet, spent. It was time to call in reinforcements.
"John! Your son requires your assistance!"
"Why is it that our son always turns into my son when he's acting up?" John said upon entering the bathroom.
"He learns that from you, you know," John added, gesturing to the sulking boy. Sherlock rolled his eyes in response and the two got to work.
And that is the story of how it took the combined forces of a consulting detective, an army doctor, and a yellow rubber duck to successfully get a four-year-old in the bath.
Author's Note: It was tough to cut this down from its original 281 to 221, but there ya have it! Hope you enjoyed this random piece of parent!lock fluff :D Feedback is, as always, extremely appreciated :)
