Should I get child services involved with my family issues?
Do you think any child is at risk in your home?
Not really, but my dad is scaring my brother
It is good to want to help and protect your brother. Scaring kids is not a crime so you should call child services only if you think it's abusive.
So I should tolerate everything and never involve CPS?
If your dad is just scaring your brother it's not needed but if he's being abusive towards him you definitely should call CPS on your dad. You're a good brother who wants to take action to protect your brother.
