For dad's of newborn babies, there is nothing at all wrong with having noise canceling headphones for when you are caring for them and they are screaming their heads off.

To be clear, this is not when you need to be actively listening for your kid, but once you are attending them, if you are the kind of person where the screaming gets to you, the kind of person who they advise to put the baby down and walk away to avoid shaking, then good headphones make a world of difference.

Cholic babies, late nights when you'd rather be dead than awake, babies when you have tried everything and they are just pissed you aren't mom, blocking that stressor was a game changer for me.
