I have an only child of 4 years old, she has attended school nursery afternoons for the last year. She has a special friend, who she used to attend private nursey b4 school nursey started, this friend attended the morning sessions. Both were well behaved throughout the year. They are due to start reception in September and are in the same class. When they get together their behaviour changes they become very naughty and they ignore any adult authority, both parents or any groups they attend. They have plans to be wild at school, we have seperated them again, but this is not a long term solution. They promise to be good but immediately play up once together. Short of changing schools any ideas.
