Son 13 newly diagnosed ASD, do i tell him?

Hello,

Newbie here!

My son is 13 and i have just had confirmation that he indeed has ASD.

My question is do i tell him? Obviously this is a yes.

My new question - how do i tell him?

I want to make it as easy for him as possible, can you guys give me tips of things that worked for you vs things not to do?

Thanks for any help at all. <3
