to this:
When I was 14-15, my mom read the book What to do if your child makes you crazy.
That’s basically all I need to know about my teenage years.

Ed Le Shan "When Your Child Makes You Crazy" A wonderful book, I read it for the first time when my older son was 2 years old.
In the following years, I re-read it several times.
This is basically all I need to know about my kids.
