My "common sense" (IMHO) suggestions from the perspective of a parent of a 5yo (i.e. not in the "socializing with friends online" stage yet):

- "Screen time" is not a natural category. You can watch TV, listen to music, read, socialize, make things, educate yourself, and play games using many kinds of screens and non-screens. Use your common sense to think about how much time is reasonable to do any specific activity. Decide what you think and then enforce it.

- Everything in moderation. Rarely was someone worse off because they did something they enjoyed for half an hour a day.

- Your kid is going to want to imitate you. If you personally aren't happy with how you spend your time, then fix it, and your fixing will do double duty.

- The fundamental question is how you want to balance giving your kid time to do the stuff they enjoy, versus doing stuff that you think educates them, expands their horizons, or otherwise builds character somehow.
