Lol no it isn't. Stop linking your account to smart devices and stop enabling one click ordering. Never give a child access to a credit card without preset spending limits.

What advertisement have you ever seen that said "don't log out of your website accounts, and additionally don't have separate computer accounts for your children's use"?

There's a lot of nudging to log in and enable stuff to facilitate impulse buys. Even little things like when you log in, it stays logged on afterwards.
