Hi Trace2, it's great she's starting so young, DS2 was about 8 or so months when he started (back in July).
She put him on the floor and looked at what he was capable of. He was very stiff, particularly in the arms, so she tried to loosen them up a bit by doing basic stretches. I think she tried to see what he could do on his tummy (not much at the time).
Are you seeing a private physio, or is it an NHS one?
All the best, hopefully you will have a great physio who will in a short time have a really good understanding of your DD's issues, and can put together a good programme, and also see you and DD often.
