We took our 10mo. old EM to the lake this past weekend for the first time and he LOVED the water. He wouldn't get out and he became exhausted swimming, and could hardly keep his head above water. Both my husband and I thought he would drown, we had to go in after him and drag him to shore. He needs a life vest. Anyone know where I can get a good quality one for his size/wt. He weighs about 140lbs. Thanks
