DD1 has behavioural problems as part of her overall dx.
DD2 started preschool 2 weeks ago, and has started copying DD1 - running around during the sitting down times, etc.
Preschool say they will 'persevere a bit longer', but I don't know what the result will be if DD2 doesn't settle down
She is such a placid little thing if she isn't with DD1.
