LOUD Parents!!

[Lee-Bee]

If in person is too uncomfortable for you, I'd just throw a blurb in the monthly newsletter or a mass email or text to everyone explaining the situation and ask for quiet drop off's

This may work but odds are it won't. In my experience naturally LOUD people do not realize they are loud. They do not realize the impact of their volume until told flat out. You don't need to be cruel about it but do need to be direct if you expect change. If it is truly bothering the OP and it is impacting her family then it isn't fair to the family to dance around the topic while expecting change. It isn't fair to the sleeping people or OP either! They may very well just assume the other parents are the loud ones...because they are being their usual volume and odds are no one has told them how loud they truly are!
