:ninja: You know what? I'll give you stretch.
Baby Naruto was actually nursed by Sasuke's mom since she's good friends with Kushina. Sasuke and Naruto initally grew up together, further emphasizing the whole "brother" symbolism. Sadly, Uchihas received great pressure from Konoha society and was accused for planning something by using Naruto, so they had Shisui used Kotoamatsukami on Naruto and made him believe that he was completely alone from the start, also on Sasuke to make him completely forget he grew up together with Naruto. Itachi just can pretend that was the case because he's good at it. Naruto was later given an apartment so he can live alone, and the money used for his daily lives all taken from Minato and Kushina's bank account. Then, Uchiha Massacre took place and everything related to Naruto's early childhood died with them.
End of story.
That is totally something Kishi would do. But it would create some unexplained stuff. Like, why would Naruto be given to the Uchiha to be taken care of? Sarutobi suspected them just like anyone else. Plus the dumb villagers didn't know that Naruto was Kushina's son, so they would wonder why give him to the main Uchiha family. Then again, they're dumb so they probably won't question anything.
