I've been separated for about two years now; as any part-time custodial parent will tell you, it can be tricky to communicate with the kids when you're not around as much. This past Christmas I decided to get an iPod touch for each of my kids. At the time, they were living about 30 minutes away from me, and for whatever reason we didn't always have nightly phone calls to stay connected.
"If only there was some easier way to stay in contact," I thought, "then they won't have to miss me as bad." Well, the experiment has been a success. In the process it yielded a few interesting tips for divorced parents, and also anyone considering an iPod touch for a kid under 11 (as both of mine are).
I do recommend that parents think hard about getting their kids iOS devices before making the leap. Most kids I have met under 10 are not responsible enough to "own" an iPod touch without a lot of supervision.
