We live in a European country. My DD just told me that her 9 year-old school friend looks after her 1 year-old sibling for hours at a time. School finishes at 12 and then someone is home early evening. DD thinks around 6. I am unsure if it is everyday. Both parents are immigrants (Chinese and Vietnamese background) and I wondered if this was something more acceptable in these countries. Regardless, I am going to have to do something.
