My son went 2 weeks with little movement through that time I tried everything to get him to move it was hard I was scared out of my mind and didn't know what to do when they looked at him he looked good.. 2 days ago I started to drink a lot of ice cold water yesterday his movements stared to go back to normal today he is moving like he use to would this be because on the water?...
