Her kids are basically engineered to do what Mummy asks them to do, mostly for the YT content. It's sad really. I used to be on the fence as well about her, thought she had a really 'perfect' little family life but eventually she started to grate on me. Her voice, her repetitive content and I soon enough saw that her children were unknowingly missing out on things largely because of her control-freak-ness and for the sake to keeping Zara from whinging/moaning, which she would do a LOT of otherwise.
I think she's a nice person, just recently got VERY carried away and desperate for free holidays/Disney stuff/anything free to the point that it's spoiled her channel and her following. Suppose that's what 'fame' and social media does to you, it's just a shame really.
