Are there health concerns with having babies, who are not potty trained, in the pool?

Students swim with a double layer of protection in the form washable swim diapers. The disposable swim diapers do not contain urine or feces effectively. Each child’s bowel and urine habits are charted on a BUDS sheet such that lesson times can be scheduled accordingly. Children swim for 10 minutes or less each day, in water that is less than 88 degrees F.
