Difficulty adjusting to change, advise please

[DaycareMiss]

Hey folks, I gave an issue that I'd like some advise on. It's been going on got a few months. I have an 1.5 year old that has a complete meltdown every time something changes during the day. The meltdown consists of throwing herself on the floor/grass/driveway/sidewalk etc. and screaming/whining/kicking feet, sometimes she even injures herself on the way down. I know this is a fairly normal thing to happen once in a while, but 10-15 times a day?? Some of the other kids are picking up on it and they too get ignored to the best of my ability definatly not a habit other parents want their kids to pick up on.. The meltdowns occurs under the following instances: getting told "no no", time to eat, time to go outside, time to go inside, time to go downstairs, time to clean up, time for a clean bum, she freaks out when parents pick up other children & Even when her parents arrive she has a meltdown. *Sigh* any suggestions would be greatly appreciated.
