How can I log out on my facebook mobile?

Open facebook in another browser, then choose the option logout from other devices. and then login with your account details.

Try clearing cache, cookies, form data, history, and everything else you can find. That usually does the trick.

once login your daughters fb from another browser or device then change the password the fine next second your daughters account will be logged out automatically!
then you can acces your fb from your mobile!!!!!!
