Dads, what "house rules" do you have?

Hi Dads,

I'm planning to introduce "house rules" in the family once our 3yo is old enough to understand them. These will be like non-negotiables to be followed by all, including me of course.

What are some of your rules that you'd like to share?

I can begin with some that I'm thinking about:

1. There are no secrets, only surprises.
2. Assume good intentions.
3. No one gets scolded for telling the truth.
4. Criticize the behaviour, not the person.

What do y'all think?
