WestieMamma I also want to give you some encouragement. It sounds like you are clearly a great mum who very much loves her child, with lots of support around you from good and varied professionals which should go well in your favour.
Awareness will be your greatest ally, and if anything, there is more awareness now into concerns around how cases are managed than ever before, and that's a good thing if you should have any concerns with the way things are handled. Seek as much advice and support as you possibly can and continue to work with services. Do you have a good advocate who can make sure you get your points across?
I believe there are support forums for people who are going through similar, some will be better than others so do your research, but some offer good support from parents who have been through what you are, and have succeeded in keeping their children and now advocate for others.
But it is certainly cases like yours, where there are differences in opinion between adult and children services where I personally believe better and independent scrutiny needs to take place. Sometimes teams can be under the same management umbrella, which is fine if all is going well but possibly not if you're not in an area where there is a history of bullying from the top down - so do your research.
Speak to your solicitor if you have concerns around this, it might be in your favour to get as many truly independent assessments as you can to use in court. Be proactive and I wish you lots of luck. (I have experienced supporting someone through similar and have also worked myself in LA so know a bit about how they work, and also in the vol sector supporting community efforts to broaden multi-agency working, so have seen what can go on).
I can't vouch for John Hemming as no dealings with him, but he may well be able to point you towards good and well-practiced solicitors.
