I'll be honest I started watching Big Brother at about 12 or 11. My mum started letting me watch the edited versions of BB10 and I loved the show and she eventually let me watch a live eviction (Angel went
) so I guess it is about maturity.
The 5 year old watching ěs crazy though. Won't pass comment on her parenting though but I wouldn't sit a 5 year old in front of BB.
