Can I swap email address that kids are linked too?

But doesn't the link/guide provided by An Xbox Dude involve changing my actual email to another one. Because if that's the case then I don't want to change my email address. I like it as it is. Or am I misunderstanding something? Does this process actually
swap my work email for my casual email and will I end up receiving work related emails to my casual email address because of the swap? Slightly confused.

for me to change the email address my account is linked too i need to it again sends and authorization code to the email address i can no longer access...

The best thing I would suggest you to do is to add a phone number or an alternative email address on the accounts. It can be your phone number and email. This way if you forget the kid account email address or password, you can use your phone or email to receive a reset link and will not even need the recovery form.

Yeah I can at Xbox live.

Erm Yeah I think i swapped email address yeah

you can't swap them, the microsoft account is the xbox account is the email, they are one in the same.
