I am living proof that a childhood filled with hours in front of a screen can still lead to being a successful adult.
The last doctor visit I went to with my then 4 year-old child one of the important medical advices she bestowed to me was to limit screen time. Ideally to zero.
I bet she could feel the shockwaves of my imaginary eye-roll.
I think my only concern is that if my kid is in front of a screen I’d rather they were playing a video game and not watching a TV show.
The only thing better than letting your kid play video games is to play video games with them.
