I hated #1. If the phone was a gift, it is the boy's, not the mom's. If it isn't a gift, then don't start off by saying "You are now the proud owner of an iPhone." Also, if it is a gift, he should be able to choose if he wants to replace it or not if it gets broken. Of course, mom should tell him "this is the only phone I will give you as a gift. If anything happens to it, you are the one who will have to repair it, replace it or make do without it" but it should be his choice.
I disagree with "Do not ever ignore a phone call if the screen reads 'Mom' or 'Dad.' Not ever." If, for example, he forgot to turn off the phone before going to the movies, he should not answer Mom or Dad. Or in class, during a doctor's appointment, while having dinner at a nice restaurant (if, for example, his friend's parents take them). Of course, the phone should have been off but the correct action in these case would be turn it off instead of answering.
Why wonder without googling? Appreciate the moment, see the beauty and research why it works that way. I would always incentive a child to google and learn.
I love 18!
