Hi. My DS is 11 months old next week and cannot sit up without support, roll from back to front, crawl, pull himself up on furniture, basically make any attempts to move. He can weight bear on his legs for a couple of seconds before they bend. We paid privately to see an osteopath as our hospital referral was taking ages and she said he has a curved spine and twisted ribs. X rays have been done now which show they are fine so that isn’t the case. We have been seen twice now by the hospital and the first consultant said that he has high muscle tone around his chest area from having reflux previously which is probably preventing him from sitting. The second consultant we saw noticed that when I was playing on the floor with DS, I sit with my legs bent in a W shape. I have done this all my life and people used to comment on it and think it was strange but I’d never really looked into it, I just feel comfortable sat that way. She said that I probably have hyper mobile joints in my hips and knees and it’s hereditary so DS probably has this too which is why he has delayed development. He has been referred for urgent physio due to his age and this starts on Friday so I’m hoping I’ll find out more then, but does this sound like hyper mobility? What might it mean for his development? At the moment I’m scared he’ll never be able to even walk with the way things are going. He’s making no progress at all. His other areas of development are absolutely fine. I was initially worried about cerebral palsy after too much googling but all health professionals that we’ve seen have said they’re confident it’s not that. But if physio is unsuccessful then the next step is an MRI of his brain and I’m just so scared.
