TBH as some one who as worked with children's services I can say her behaviour would have to be a lot more extreme (and actually have happened )
Her child Looks fed, clean and well cared for and I assume doesn't turn up at school stinking of weed. She, as far as we are aware, neither takes or deals drugs, She doesn't leave him alone at home or with random strangers, as far as we know she doesn't bring strangers home to have sex with them while her son is there. As a someone with foster siblings she will have seen positive parenting.
Also. At her son's age, his opinions would be taken very much in to consideration
I am not saying she an amazing parent, and she has made some very public errors, but she is honestly a very long way from losing care of her son. And that stuff about her son watching her breathe is obvious bollocks. I really think she as painted herself in to a corner. Either look like a slightly shit parent, or admit she is a liar.
