No More Sippy Cup?

Last Friday, Sweet Pea's daycare sent all of her stuff home in preparation to promote her to the two-year-old classroom. She will be two on August 10th (I didn't have to think twice about her birthday, usually it takes me few seconds to remember, sad, I know). So, on Monday I sent back all of her stuff, including her sippy cup. On Monday afternoon, the daycare sent back her sippy cup in her lunch bag. Hubby and I just assumed the new teacher did not know that her sippy cup stays at school. Later, we find out that they are no longer using sippy cups, they give them cups to drink their milk and juice out of. What is that? My Sweet Pea is not even two yet. I should have gotten a clue from all the times she drank out of my glass without any accidents. I am not ready for all of these changes. I just convinced myself to start potty training her after she showed signs of being ready for a couple of months now. Ugh, where is my baby going?
