Is there any way of manually updating games when I WANT TO?

Disable "Always On" which will stop updates from downloading but when a game is launched it will try to update if one exists and if your son accepts it, it will start the download.

I have Comcast and luckily they haven't implemented the data caps here yet. But one option is to pay the $35 extra a month to get unlimited data on Xfinity (customer.xfinity.com/.../exp-unlimited-data).
They recently dropped the price of the 150mbps so I called them and almost halved my bill which is more than enough to then buy the unlimited data add-on.

Hello There, I'm happy to try to help you with your problem that keeps consisting with your question. There is NO other way to update the game when you want to but the only way to avoid updates is by not being connected to the Internet.

Hey Tobs,

Once a date of birth has been set on an Xbox Live account, it cannot be changed. You can update your date of birth on your Microsoft Account, however Xbox Live will still look at the original birthdate set.

Hope this helps clear up the issue.
