I want my mother to create her account by herself
Why would you want your mother to create the account?
I just want to see what she could actually do by herself.
It's good to try and help your mother do things by herself. That helps her in the long run.
Yeah but I won't help her. She's should learn on her own.
She won't be able to do it by herself without you teaching her first. You should show her a couple of times then watch her do it by herself and correct her if she does something wrong. Don't forget to also show patience.
