She's been with me for 2.5 months. I'll take your advice, and sit with her for a while to try to stop it while it's happening. I'm usually always on the move during meal times, getting refills for kids, and trying to keep it as tidy as I can, but if I can try to correct it, it would be time well invested.

I always hate conversations like these with the parents...if I don't see an improvement in a few weeks with me working with her, I'll talk to them.

Thank you for confirming what I was thinking everyone!
