Well, it seems the parents were overwhelmed with all the birthday planning had to deal with... that is why I go to the high school, and hire two childcare provider students, and offer to write a evaluation for their services for their class. They provide the hands, eyes, ears, and legs, when I need them, I hire two people per the party area size, if it is outdoors, I hire up to four, and assigneach worker a certain number of tables to handle, they are younger and more agile than me, and I explian the party rules to them to enforce... One of the workers stays near me for switch off duty... If my friend has a special needs child, I even offer them a "respite day," by giving them a "worker," to handle their child, so they can relax, and enjoy themselves... However, I do require the attending parents to corral their children, since they set their own social rules for their family. however, if their child is out of control, I will ask the attending parent to take their child out, until, they can maintain social decorum, so that EVERYONE can enjoy the party. My friends know me, so they know, I will not tolerate anti-social behavior. I think these parents did not have any activities to entertain the children, and as an attendee, I have "saved," parents from party meltdowns, but, taking over an child activity, which brought some organization, because just like you, they are new to it, too! My first party was a mess, but, the kids had fun, because the parents helped me! The puch bowl table fell, and splashed everywhere! Luckily we were outside! One of the parents ran to the store and got me a replacement punch bowl, at home, and another made cooler punch with packages of kool-aid! We rotated the party to avoid the spill area. I think you needed to relax, and if it got to hectic, you could have used those nails to assist the parents, since we all have to learn... It seems your son was partiicpating in the ruckus, since he fell on the vomitus, which any parent should have cleaned up! The inclusion of music would have gotten the energy level down, if "someone," had made a dancing area for the kids. Being a parent means you need to learn how to relax, because as humans we do not have a pouch to carry our "joeys or jocelyns," we all have to learn how to let go, with supportive, creative ways to assist, rather than sit back, and assess... sorry, but, when it comes to parent-kid events, most parents think that it limits their ability to keep control of even their own kids... I just switched a paradigm, but, showing you that there were other ways to handle the event occurrences, whether good or bad, but, your son was included, thought it might not have been what you expected... Maybe, next time you could contact the parent offering the party, and ask, if there is any assistance you could provide at the event for them... That would keep the nervousness down, and while you are helping, you will have some control over the "safety issues," while remembering, the event is suppose to be fun! Besides, when was the last time you got hit with a balloon? Maybe, you should give one of your son, and both of you take turns being silly, hitting each other, as you laugh, remembering that being a prent, isn't always SOOOO serious, it is a journey teaching your offspring, that they are loved, cherished, supported, and allowed to experience life with a nervous Mother, praying that his or her wings work for that first flight... It seems you have a good beginning, because your son, was able to enjoy himself, oblivious to the "emergencies," you saw... Next time, stay, and help... Allow him to see "life," by what is expected and accepted socially, sometimes life isn't perfect... And having the cake is the most important part FOR A CHILD, you might not of cared, but, from his young eyes, this was a definite moment to give your adversial words or tears... You could have waited... Sorry, Mommy, having a boy means there will be the need for bandages, and unexpected things... including vomitus, things in orifices, and damaged bones, muscles, and skin... But, hitting with balloons, isn't dangerous, until they were eating them... Then, we have an issue...
