I think my son (age 5, year 1) is hypemobile in his hands can bend thumb back to touch wrist, very bendy fingers, can bend fingers back beyond 90 degrees etc. He doesn't seem particularly hypermobile elsewhere and doesn't complain of any pains anywhere. He is a bit uncoordinated though, struggles to hold a pen properly, and dislikes any sort of drawing or writing (he finds it very tiring). Anyhow, am just wondering what to do should we visit the GP or just mention it to the school, even though it's not diagnosed?
