My son has hypermobility too but his is in his minor joints not major ones so like wrists, knuckles, finger joints etc. Sleep is never an issue with that, he does however have ADHD and that does cause issues.is this a new diagnosis now, it’s not restless legs, it’s hypermobility now?
My LG doesn’t have sleep problems either, her hypermobility in her feet stops her walking during the day, if I remember poppy is a good walker, surely she’d complain after walking a while if it was painful,
