You can't discipline her like a typical teen and ground her. They could be consistent with their response.. stop calling it quirky and cute. When she strips.. stop everything and make her put her clothes back on... period.. Certain places and people are ok to be naked and some are not.. and set that consistently.Oh for gods sake. Even toddlers understand discipline. They are simply too fearful of her tantrums. She runs that house. Even something as small as her getting annoyed when P touched the bike....P instantly jumps back..."ok ok!"....like they are dealing with a mountain lion. Shows how they jump through hoops just to have a "good day".
Same with other behaviors, when she steals food .. dont laugh and call it cute or have her do it for the VLOG and reinforce it.
Take her to the bathroom on a consistent schedule and every time she signs bathroom... etc
Its really all about content for the VLOG and extreme laziness.
