DD is hypermobile and has poor core strength. Getting her to sit at the table and eat is a bit of a nightmare. She has a barstool type highchair to make it easier for her but it hasn't helped that much. She ends up flopped all over the place, with one foot (or both feet) on the floor, kind of diagonal. I'm concerned she'll have more trouble when she moves up the school as she'll probably be called upon to sit still for longer than at present.
Is there anything anyone's tried that's worked? Would it be better raising an adult sized chair so there's a wider base for her to sit on? Any exercises to help sitting in particular? She does swimming etc. We have OT support but due to cuts it's impossible to pin them down at the moment.
