I'm really not worried about it, it's just that the Gymbaroo leader made me feel like it might be something to be concerned about. DH has climbed a mountain and gone abseiling and runs his own business so I don't think his lack of crawling has affected his physical or mental agility at all!

I'm taking DS to his osteopath tomorrow to just check up on this because I know DS has some residual tension in his pelvis from his delivery (which was already being treated) but I'm sure he is fine.
