Re: Play date etiquette ??
My dd is 6. When we do playdates, some people drop off and some don't. I never drop off b/c my dd has life-threatening food allergies. But I just explain to the other parent that, because of her medical issues, I don't do drop-offs and that I'm happy to bring a book or work and they don't need to feel compelled to entertain me.
I wouldn't care at all if another parent wanted to stay. I WOULD care if they brought a bunch of kids without telling me ahead of time. I would just chat with the mom and see what she had in mind. If you're not comfortable with a drop-off and don't have care for your other kids, why not just invite them over to your house?
