The blindside being the unique tone of the episode, compared to what came before it. It still has silliness and is a fun watch.

Some things that I think make it hit differently:

* The house and most scenes are dimly lit

* You see the family in various stages of sleep

* The musical score has some intense crescendo

* The vulnerability it shows

It's a small glimpse of night time in a house with a child that is still transitioning to sleeping on their own. Having had kids, that weight being lifted as they finally "get it" is a unique feeling of bittersweet relief. It also shows the lengths the parents go through to make it a graceful and comforting transition.
