Hi,

My daughter has a disability, her current diagnosis is Cerebral palsy, autistic tendencies and intellectual disability, although these are really just 'labels' to access funding. My personal opinion is the diagnosis isnt the be all and end all, it just helps sometimes to get extra funding for things and an idea of what to expect in her future.

My daughter did have an MRI when she was about 2yrs old, it is always horrible watching your baby go under but in our situation I considered it was worth while, it did rule out a few different diagnosis' but It didnt give any answers as to what the problems were, it has been useful down the track to monitor development.
She hasn't had a lumber puncture so not sure about that one.

I do want to say though, it sounds like you and your support team have done wonderful work with implementing the therapy programs and had some wonderful results. I think early education is so important, I wish my daughter was able to get better early therapies to develop her skills.
Of all the people I know in the 'disability world' the kids who seam to gain skills and amaze everyone with achievements not thought possible are those children whose parents have made the most of all therapy programs available and continued programs at home as well as during therapy sessions.

Good luck with everything, you sound like you are doing amazing work with your little girl.
