My child is going to start high school this year and iPad is a requirement at the school. I went to the iPad setup session at the school and while doing it, we were told that the child needs to have their own Apple ID.
However, as my child does not turn 13 until later this year, and for other kids in the same situation we were told to just select a birth year that will make them 13 on that day, so everyone selected a year earlier than the actual birth year in order to create the Apple ID.
My question is whether it is legal to do it and what kind of values we are imparting in the kids - just lie to work around restrictions.
In my opinion, if the kids are not 13 don't force iPads on them until they reach that age.
