I agree with Lou. Drop offs need to be super quick regardless of screaming or not. Hug and kiss and gone...the longer they linger the worse it will be. As for the food issue, just put the food in front of her and then leave her be, I wouldn't even ask her to take a bite or even make eye contact. Soon you will find she will start sneaking. Bites and then before long she will be eating full meal but even then I wouldn't raise notice to it either. I would give it at least 2 more weeks with the quick drop offs and see how that goes. Good luck, we have all been there at least once.
