TBH aranea, I don't believe there is such a thing as mild Aspergers, in order to get a dx of aspergers or high functioning autism you child's difficulties are seriously effecting their daily life.
How does your Dd cope with changes in her routine. Can she cope with sensory stuff eg bright lights, loud noises, itchy clothing?
You say she has a good imagination, my Dd3 gives the impression of playing imaginativly[sp] but actually what she does is replays situations she has been in, usually at school. She plays repetetivly[sp].
Does your Dd like to watch or listen to the same things over and over again?
What is her Theory of Mind like, can she put herself into someone elses shoes? Does she expect you to know what she is thinking?
If you are worried why not go to your GP with your concerns, there is no way your Dd would be dx'ed with Aspergers unless she actually has it. It took us 3.5 years and much fighting to get Dd3 dx'ed .
The proffs are reluctant to label children atm, if you think your Dd will struggle i secondary you should start the process now.
you could re post this in the Special needs children section, there are loads of really knowledgable people over there and I am sure you will get good advice.
Good luck
