Parents who shove tablets or phones in their kids' faces. Kids nowadays need to learn how to entertain themselves and regulate their emotions rather than mindlessly scroll at 2 years old. I personally think parents who do this are taking the lazy way out and are just allowing the tablet to parent for them; there is no discussion or creativity taking place.

And you feel terrible for snapping at them. Again. Maybe you believe that good parents sacrifice everything for their children. That putting yourself first is selfish. That if you just tried harder...had more patience...were a better person...you wouldn't lose it over something so small.
