Transparent therapy ball on tfh website-which size? It says choose ball the same diamoeter as the users arm length but there are no measurements on there! Anyone help?

Dd is five but the size of a 7 year old. I am tempted to go for medium but if tfl caters for adults too then medium may be too big. Anyone got one of these?

ds2 uses one at OT & its massive, he lies over the top of it & doesnt touch the floor so has to be lifted on top. I guess it depends what you need to use it for?

It is also for OT excercises. So she would be rolling over the top to reach objects on the floor whilst blowing a whistle(eventually). Also for some physio stuff but most importantly for now the OT so I guess it can be quite big for her too.

The TFS site is a bit confusing, they say about not hurting your back by having the right size then I was left unclear as to whether it should be one arms length diameter or both, and then no measurements! I have given up gor the night but did order a load of sensory toys from amazon for her stocking so a good net session!
