Also if the children are using it make shaw you have a password on the app market and also set it up so it requires a password for any payment.
I downloaded a free game for my girls but they accidently managed to purchase some "game credit" which of course cost us.
I have locked it down so cant happen again but can be a trap although it is a pain when I want an app but better safe than broke.
This is very very very good advice, try telling your wife it was not you who downloaded the adult content app. Then your 6 y/o tells you there is a mummy and daddy game on the ipad.
Oh yeah it's happened. ( not me a mate ) yeah right
Lock the app store with a password and also watch out for your home wifi network , ours hooks up as soon as we walk in the house so the kids can acess the home network and end up online . we now disable the wifi network unless we choose to go online. This has to be done on each ipod/pad or whatever you buy. Also watch the kids phones that have wifi they can sit in thier room hooked up to the net.
A family friend recently was shocked to find out thier daughter had been online for a year in her room because the home network had no password on it and with 200gb they left the homeshare password on a sticky note in the drawer in case they forgot it. Another family friend had to alert the parents to the acccount she had craeted on facebook etc.
