Very well said and thank you for a wonderful ost @emdesan.
I completely agree that too many people nowadays expect schools to raise their children. Even though my kids went to public school. I would go in and speak with their teachers before school started to see what kind of relationship we were going to have. I was a single mom so volunteering at the school was out of the question. Did I set up meeting and phone calls to stay on top of what my kids were doing?? YES I DID. I have had my kids placed in other classes for various reason, mostly I did not like how the teacher handled situation, such as bullying. No I only did this one with each kid. One was the teacher was actually abusive to my daughter. My son was being bullied by another student and the teacher did nothing, so we changed classes luckily the issues were resolved.
Believe it or not how you work with your child with school and homework, lays a foundation of self-esteem and work ethic. When your children see you're dedicated to them even though you do not get to spend the time with them that either of you need or deserve. They KNOW no matter what you are there for them, you support them.
