Sasuke did not like the baby.
The noises it makes irritate him.
The dirty nappies make him nauseous.
Watching it eat, now that it eats, also make him nauseous.
Its hands get into everything dirty and sickly and then touch him.
It's way of commutating is frustrating.
Naruto is never without it.
Not ever.
All he wants is his stupid little Naruto back.
But…
Even though Naruto can't spell or use a smart phone or tie his own shoe laces and didn't know where babies came until he made one, Naruto is not stupid anymore.
