Oh my it sounds like you have alot on your plate already. I understand why you want to take on the leader position but to me it sounds like you have so much else going on that this new responsibility would probably cause more issues than it's worth. Just my opinion though, trying to think of what I would do in that position. Have you spoken with the other parents to see what they are thinking and if any of them are contemplating taking on this position as well? Maybe if other parents are considering doing it as well you can offer to help them when you can, knowing they have support may make any parents considering this want to do it.
