Clarification
I've read all the posts on this thread and I don't think anyone has clearly described how iCloud, the App and iTunes stores, and Apple IDs work.
The key thing to remember is that you can set up a device using one Apple ID for iCloud (syncing, backups, Photo Stream etc.) and a DIFFERENT Apple ID for making purchases in the App Store and iTunes. This makes setting up a device for a child very easy:
1) Create an Apple ID for the child
2) When setting up the new device, use the child's Apple ID. This Apple ID will be the one iCloud account on the device.
3) Once the device is set up, log out of iTunes and the App Store and log back in using your (parent) Apple ID.
Now the child will be using your Apple ID account for downloading content, and his/her own Apple ID account for iCloud syncing and backups. You can go into FaceTime and iMessage settings to make sure that your child's Apple ID is being used for those functions (which they should if you follow steps 1 and 2).
You can prevent your child from purchasing content in iTunes and the App Store in the Restrictions area under Settings on the device.
