Today DS went to a birthday party for a little boy in DS's preschool who was turning 5. There were 8 kids and we were the ONLY parents who stayed. DS is 4 and was definitely not the youngest child there. We know the parents of the birthday boy only casually though preschool and they seemed pretty surprised that we were staying. I made an excuse and said that we'd stay becuase sometimes DS gets worried when he can't find us (totally not true). The party was absolutely great and I suppose I could have just dropped him off.
So at what age do you feel comfortable with just dropping your child off at a party? I'm wondering becuase not only do I feel like I breached some sort of unspoken etiquette, but I also want to know what to expect when we host a Halloween party next month.
