Age 5 is to young for a Tanning bed. If they are 15 and old I say they can go to the TB with there parent or legal gaurdian permission, They too must be present. If they are allowed to have sex at age 15 then they should get the bed as well.
Now that is disturbing!! for crying out loud, you do not put a 5 year old in a tanning bed!! their skin can't handle it and at that age more prone to get skin cancer!! That lady is going to suffer a lot as she gets older from all that tanning!!
That mother looks like a walking piece of jerky. That or a dead husk, either way it doesn't look like she can move much because of how leathery her skin looks. Honestly that should be a clear sign to the authorities that this woman has real problems if she tans that much.
