"Hold off giving your child a mobile phone for as long as possible: Maté is reluctant to be prescriptive as far as technology is concerned"
Seems like the end was cut off somewhat (no elaboration or full stop). Hmmm, I get that the author won't want to give too much away in interviews because he wants people to actually buy the book, but I found all a bit vague. Don't nag or try to control, spend time with your children, and make more effort. Is that the gist of it?
