Is YouTube good for kids?

Youtube is good for children because you can show them tv shows and songs to help them learn their ABC's for examples. These videos for KIDS (you shouldn't show them the videos YOU want to watch unless they're appropriate for children) will make the child happy and possibly smarter.

On the other hand, showing little kids youtube will ruin their eyesight at a small age, making them have to wear glasses sooner. Also, in some videos, there are asses that put disturbing and scared things in the videos people would show their toddlers, thus having the toddler traumatized and / or giving them nightmares. To try to avoid this, perhaps you could watch the videos you'd want to show the kid(s) before you let them watch them.
