children on deck at workouts

Hi all, I am the president of my team, and we recently instituted a policy after having an increasing number of parents bringing children along to workout. (Usually in the case of both parents being swimmers, and one swims while the other watches the child, and then they switch off for the next workout.) We found a need to institute a policy after seeing a wide range of what parents considered to be acceptable behavior, and to be an acceptable level of supervision. I am wondering if any of you would be willing to share any info about this subject at your team. I am wondering: - Are members at your team allowed to bring children with them to workouts? - Does your team have a written policy about this subject (for example, child must have an adult supervising them, child cannot be within a certain distance of the pool, etc.)? If so, can you share the wording of that policy? Thanks for any info!
