What do you consider your most important parental responsibility toward your child?

I'm definitely not a parent, but the best things I'd do are among the following

Shielding their eyes from things on the internet, such as adult sites, etc.

Keeping a nice sleep schedule both to calm me and he/she down for school.

Keeping up with their basic needs such as food, water, shelter, etc.

Teach them respect through anyway (except for disciplinary esc action).

well when looking at this if you think about it   negativley and positivley   react with each other and when the first layer gets full they add layers it starts with 2 on the first layer and it constantly goes on until the official number is there
