Every parent is required to say they only allow very limited screen time even if secretly they all allow quite a bit more.
We stick to the 2x30 minutes rule for 90% of the time but we do make occasional exceptions like when they're ill.
Might change when they get older though.
It's not a challenge to keep a limit on screen time at this age.
Good for you.
It is, however, a challenge for us.
If all your friends have the same rules as you, then great. If all your friends have no rules at all, you are a tyrant, and your child will be at his friends places as much as possible.
