I have sent you a PM.

There are some similarities between your child and my daughter.
Her current diagnosis is apraxia.

Have you looked at apraxia at all? If not, I'd recommend at least looking into that.

There is also some overlap with apraxia/asperger's, in regards to some of the 'soft' signs of apraxia, such as the potential for sensory items.

My daughter does NOT fit all the signs of apraxia, but when diagnosed, they did explain to me that apraxia is a spectrum.
