My twins were born at 30 weeks and there seemed to be quite a bit of concern shown for my daughter at first as she was twin 2 and born by emergency c-section due to drop in heart rate. They both spent 7 weeks in scbu. They are now 17 weeks old and at our consultant appointment this week he seemed concerned by my sons stiff arms and legs. They arent completely rigid - I'm now watching him waving arms and legs whilst under the play gym, but feel stiffer than his sisters. He also seems quieter. Having said that he seemed to start smiling about 3 weeksago though not often and has twice rolled from front to back. I'd really appreciate any advice as I'm worrying myself crazy at the moment - thanks
