Disclaimer: Naruto isn't mine
Being a dad means listening to a woman —who has vowed for nine months that she wants natural childbirth - scream for pain relief after ten minutes of hard labor. It's okay. Her doctors won't be surprised.
As soon as Naruto found out that he was pregnant, he repeated one simple mantra. Don't give into medication. He didn't want the baby to come out messed up or demented or some drugged up newborn. He wanted the baby to come out with a clear head.
That lasted for ten minutes, ten measly minutes until Naruto began yelling for drugs. Sasuke was embarrassed to death. This wasn't Uchiha behavior. This was very much Uzumaki behavior. The doctors on the other hand didn't even bat an eyelash to Naruto's behavior. They rest assured Sasuke that this was normal behavior and they were more than used to it.
Still, it wasn't what Uchihas behaved like!
