Like anything in life, it’s moderation & being sensible. There is no need to go zero screens. TV is not the devil & nor are some decent educational apps etc. You’ll have more of a battle by overthinking it & being super strict.
I don’t have limits as such, I use my own common sense to moderate. These are things I do:
My kids wake up early. On a school day, they play together until 7ish & then I do breakfast. After breakfast, they watch TV for 45 minutes or so cos it makes my life 100x easier to get them dressed, teeth done, hair done while they are chilling.
On a weekend, I’m grumpy as hell that I’m up at 6am. So it’s film morning. We cuddle & watch a Disney or Pixar while I half dose until a more reasonable time in the morning 😂
TV is not on constantly while at home. That’s a firm no (although it was during lockdown 🥴). It’s on when I need to get something done, like lunch or tea or the washing. It’s on if we’ve been out all day & they are tired & need downtime. Otherwise it’s off & we play or draw etc.
They both have iPads. We use them on long journeys. We travel 5/6 hours in the car frequently to see family. Generally, the first couple hours they just listen to songs & chat. Then they get bored. For all our sakes, after we stop for a break, they can play games or watch TV for the rest of the journey. Similarly, we use them on flights. DD1 can’t read yet & DD2 is a toddler. Flights are boring. I read or browse my phone. Why should they sit there twiddling their thumbs? Drawing & stickers keeps them entertained for an hour or so but then what? Screens are fine to pass the time.
I have no battles with my kids at all. They accept that’s how we do life. They love to play & love to draw & love to get out the house. TV is just part of it. I don’t use it as punishment or reward etc. it’s just a thing in their lives that’s sometimes on & sometimes not..
