Playground Rules?

Most playgrounds seem to have a couple specific rules and a couple that are left up to parents to define. I've seen many that say the play area was designed for certain ages, children are to play safely, and aren't to be left unattended. Should playgrounds post more specific rules?

Take the sliding board for example. I have two children and have spent many o' days at various playgrounds and each visit we've seen children who's parent's permit them to go up the slide, and parent's who do not allow this. Why some parents see it as more of a safety concern as opposed to misuse of equipment.

Then there are the swings. Playgrounds just don't seem to have enough swings. Children will wait and wait, only to have spent their time waiting and not playing because they wanted a turn on the swings. Should there be a time limit?

Then there are the parents who allow their younger child to play on the equipment meant for older children because big brother or big sister is with them, and all the while they fuss about the older children not being cautious around their little one. Same rings true for the parents who allow their older child to play on the equipment meant for the smaller children.

Now, I know signs wouldn't solve all the playground issues everywhere, but I'm wondering if it would make it better. I know it's easier for me to point out a sign to my oldest and explain that's why Mommie said no!

So....comment and confess! Do you allow your child to walk up a slide or is that a no no? Have you ever allowed your child a tad longer time on the swings when others are waiting or has your child waited forever while some other child took their sweet time? Confess your playground peeves?
