I don't have any accident reports because everything that has happened has been normal bumps and bruises that parents should expect to happen when 5 busy, bouncy children are playing together. I just tell the parents about the incident at pickup time and usually they just wave it off as a regular thing, especially for the boys.

If I had a parent who made a big thing about little accidents I would ask them if they trust me or not to keep their child safe. Thankfully, my dcparents all have complete confidence in my abilities.
