I don't have advice much different than other mom's, it is good to call and find out. My son just had his 6th birthday party at a public place and the parents all asked me if it was ok to leave their children with me, I had already arranged to have a friend help me out so I had no problem keeping all of the kids without the parents. All the parties my son has been to the parents request that I just drop him off and picked him back up at the scheduled time!!
