Active Toddler

Hi there may i know if any of your lo teacher comment that your child is very active and likes to run around. Teacher said that, if she running around can harm injury herself. Not listening to anyone. My qns is, its freaking literally 3 weeks only barely in Nursery 1 for 2 hrs class. Only 12 students with 3 teachers. 60% of the student still not adapting to the environment and crying their lungs out. Teacher cannot start lesson once all the students are settled down Can any parents advise me on this what to do. Omg.
