Kate is an odd one, she was big/popular online during the youtube pony phase, of course everyone loved Nero. Her and her family seemed to live more of a normal life then. She never got the same success in the ring when she moved onto horses and that seemed to be when things started changing, collecting more horses, animals in general.
She doesn't seem to have done the normal, grow up, get a job, move out thing. Which I guess, does it matter, is that just society norms, but that's a whole other cul de sac. But all lead me to wonder if she struggles with mental health. She does seem very young for her age and have seen videos where she's sleeping in the tackroom as so much to do. I too hope both her and parents realise they should cut down on animals before baby arrives.
Baby is obviously very wanted, I hope it all goes as planned for her.
