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).
B. Between the second and the fifth intercostal spaces from the right edge of the sternum to the left midclavicular line
Authoritative parenting?? Don't judge because of my grade.
