Albaba, vent away. I have had all of those thoughts, and more about other children, at nursery and generally. Also has them about ds splints, and his kaye walker, and the standing frame. Although it sounds trite it does get easier! Although not always, and I still have those thoughts. Ds is also supposed to be mild, but he still can't walk. The real issue is that progress is slow, and always will be.
One of the best bits of advice I had was not to worry about what we should or shouldn't be doing. I do still worry of course, but I also want to be a parent not a therapist. So now I am trying to think of things I can do with ds which are fun, but which I want to do anyway, so today ds and I went to his swimming lesson. He's rubbish, but he enjoys it, I enjoy it as he's less different in a pool than on dry land, and it just so happens to be good therapy. Ditto trike etc. but if ds doesn't enjoy we don't and it becomes self perpetuating.
I was also told by an adult who has cp that they never wished their parents had done more therapy. Had more fun yes. I am not saying it works for everyone but it works for us and I just push ds to do what others do.
I fo still get a pang when I see a colleague who had a 23 seeker, who is not disabled. But that's life. It's not fair.
Thanks on the comments on the ot. That's nothing like what we get, no exercises or goals! It would be good to ask for a new ot, but that's not going to happen in my trust so tbh I would rather spend money, than time fighting the NHS. It's easier for me in the long run, and I am lucky that money isn't really an issue, but time is.
