Whatever Apple ID you add to Messages will be the one that you will send and receive messages at. You can learn more about the setup towards the bottom of this page:
iOS 6 - Messages with iMessage
So as long as your iCloud Apple ID is not added to your kids' devices, they will not receive your messages.
