My son is 6 (diagnosed 6 months ago). He LOVES to swim. Today...he actually got OUT OF THE POOL to tell me he thought he might be going low. He was at 72. I'm so proud of him for getting out of the pool! I've tried to stress how important it was to get out if he felt low, but I didn't think he would actually do it. It's the little things that make us so proud of our children!
