Sometimes-no, often-Sasuke found himself wishing that Itachi was normal. Of course he loved his older brother, but...Itachi just required so much attention. Different people had labeled him different things, ranging from medically accurate to cruel and uncalled for. Their mother, Mikoto, said that Itachi was "a bit slow". His teachers said that he was "challenged". Doctors said he was "intellectually disabled". Sasuke knew they all meant the same thing-Itachi had been in a car accident when he was a newborn, and was severely brain damaged. His IQ was 28, and he needed help with almost everything. Other seventeen year olds wrote essays and solved algebraic equations, but Itachi struggled to count to ten. Mikoto and Fugaku didn't want anything to do with their oldest son, and had considered sending him away on more than one occasion. The only thing that kept them from doing so was Sasuke, always taking care of Itachi, making sure he was healthy, keeping him out of their parents way.

"Okay, 'Tachi, which animal goes there?" Sasuke smiled encouragingly (he never smiled at anyone besides his brother) and pointed to the puzzle he was helping Itachi complete. The older boy stared at the childish game for almost a minute, before finally grabbing the cow and trying to fit it into the correct space. It took a while, but he eventually got it. Sasuke grinned and ruffled his brothers long hair. "Good job, oni-chan! That was the last piece, so it's bedtime. Do you need to be changed?" Itachi merely stared for several seconds before saying, "Dunno." Sasuke smiled patiently and walked around the table to check his brothers diaper. "Yeah, looks like you're pretty wet. Let's get you cleaned up, okay?" "Kay."

A/N: This idea has been floating around in my head for a while, and I finally decided to do something about it. I know Itachi's extremely OOC, so please don't flame me about that. If I post a second chapter, it will probably be from Itachi's point of view, but I might not do that-I'm working on two other stories at the moment, so I don't have time for much else. I do, however, want to write something involving Kabuto and ageplay, but I don't have any ideas beyond...well, Kabuto being babied by Orochimaru. Anyway, thanks for reading this!
