Officially a "BIG GIRL"

Monday was Baylee's first day in Nursery C at daycare. All About Kids is broken into 3 nurseries. A is for 6 weeks to 6 months, B is 6 months to 12 months, and C is 12 months to 18 months. They have been transitioning her since last week. Her first day in transition she came home with a large mark beside her nose. Apparently one of the older children pinched her. I have been told that there are "bullies" in C. Please tell me how BABIES between 12-18 months know how to be bullies? The pinch mark bruised and has now faded. One difference in C and B is that the kids sleep on cots and not in cribs! There are VERY low to the ground so if she did happen to roll off she probably wouldn't even realize it. On another note we are now down to 2 bottles a day. They are whole milk but still it is from a bottle. One in the morning and one at night. Saturday morning I am planning to put the milk in a sippy cup and just do the bottle at night until we run out of bottle liners. I am hoping by Monday she will be ok with having her milk from a sippy cup. Last time I tried she spit it out immediately. Here are some pictures before her first day in C at daycare. I know they aren't the best but what can you do with a VERY active one year old?
