When I rushed out the house this morning, thinking I'll take my time to try and type a 'satisfactory reply' later in the day to try and help whoever replied to my response, I actually had similar thoughts to you. Why are people seemingly hovering over these threads waiting for answers to drop in their laps. Just contact the company directly. If you have and still need answers, contact them again. It's natural to be cautious, & sceptical especially around internet ads, but you literally have nothing to lose making those calls. They aren't trawling Mumsnet looking to answer all your questions, I don't know any company that does that.
I suspect you thought the last response was from me? Possibly. It wasn't.
If you contact them directly they can listen to your particular situation and gage whether their approach would work in your circumstances.
I reached out to them when I had tried all other avenues. I think that probably put me in a good state of mind to stick with it and until we saw results.
There is structure to the mentoring sessions but with the scope to tailor and adapt to the child's own needs/pace. The parent zoom sessions which run regularly, occasionally have a theme that the host has picked up is a common issue, but generally the learning and what each parent gets from it is more organic. Families talk about the day-to-day issues/challenges/concerns, and they are guided by how best to handle those as the parent, whilst their mentors take the children on a journey from awareness of what's going on, strategies to help them cope, gradual and then building 'facing their fears' type process and loads more depending on what each child struggles with. If a parent struggles with high anxiety themselves, they will provide 1-1 help for that also.
That doesn't do it anything like justice. It is intensive. It is a commitment. If you hear all about it and have any reservations, I would suggest don't do it. It needs the parents to be fully on board. You can't just pay and expect it all to just happen, the road back isn't that easy, I'm afraid.
I'm going to take myself off Mum. Good luck.
