Disclaimer - I use Amazon a lot but don't have any sort of Kindle, or know much about them.
ExH bought DS (ten) a kindle fire hd for xmas. he set it all up for him and when DS came home I couldn't work out what he had done so just left it all. I wanted DS to be able to access stuff I buy on amazon, music etc, and couldn't find a way of getting this to work. Somehow I added my account to DS kindle so he could buy games on my account. I realise now what ExH did was set DS up with a new adult account and a fake credit card number attached. (This explains all the post I have had from Amazon addressed to DS, offering him prime...)
After an incident with DS buying stuff from my amazon account and lying about it (!), what I want to do is set him up as a child on my Amazon account so he can see content I want to share with him and I can limit what he does. I want to get rid of this adult account that has been set up in his name. Is the easiest way to do this to deregister it, or should I go back to factory settings? I know he will lose a lot of games but that's just going to have to happen I think.
Thank you. sorry for long winded post!
