Not Sure How to Address This...

My insurance states that I am responsible for anything happening on my property to anyone on my property and am covered for up to a $million I believe. Basically if something happens to that child, you can get sued.

ditto on this....I would not leave it up to the parent to decide how she is going to handle this situation, especially knowing that you can be held liable for anything that occurs on your property.

I would be telling mom exactly how you want it managed and enforce her to follow through with it.

Because this is a huge safety issue and because YOU could potentially be held liable if the child got injured on your property, you need to tell the mom that SHE needs to figure out how to manage drop offs/pick ups or you will have to term her.

Yes, this. If you know there's an unsafe situation and don't do anything about it you could be liable and be sued. What if the child locked the mom out of the van?! I'd tell her the older one has to come with her, or pick up the younger one first.
