Hello! Unfortunately I can't answer any of your questions but wanted to add that my daughter's leg measurements have also shown there to be an increase in discrepancy; her right leg has always been smaller and thinner than her left but the first time the orthotist saw her the difference was 15mm and the second time (only just over 6 months later) it was 20mm- a bit alarming. Fortunatlely, the next time she was measured, it was again about 21mm difference. Emma (will be 3yrs in September) has always worn a shoe raise since learning to walk - the orthotist confirmed it was necessary not only to help her walk confidently as well as to prevent spinal problems, but also to help strengthen her right leg and in the long term perhaps even reduce the discrepancy - though obviously the last reason has not come to pass (yet?)

I hope you receive some light on the subject - and I will be very interested to hear what others say too!

Best wishes,
Sophie
