Disclaimer: Naruto isn't mine
Being a dad means realizing your usefulness in the labor room rivals that of a lampshade. But you can be supportive.
You don't really think about a lampshade being useful. Because it really isn't useful. It only serves to make your purpose easier but you can get by just fine without using it. That is what Sasuke felt like in the labor room. A lampshade.
A lampshade couldn't help Naruto calm down. Whisper sweet nothings into his ear as your bones slowly grind to dust. Nope. A lampshade couldn't do any of that.
That didn't stop Naruto from throwing the lampshade and lamp at him.
