Hi all I'm after advice more than anything.
DD is in year 1 at school and has been bullied by the same girl since they were in nursery.
It isn't physical bullying but it is emotional and is really damaging her self esteem.
This child will form fake friendships with DD and DDs other friend and will then exclude DD on purpose from whatever activity they are doing. She will pull her friends away from her and will make it into a game where they all run away so DD is left alone for the rest of play. She also says very nasty things to her and points and laughs at her because she has an "ugly face" 
I have been speaking to the teachers constantly since they were in nursery and still this behaviours continues and DD comes home from school in tears at least twice a week 
I have now written a complaint to the head teacher who has said he will launch an investigation which I am happy about.
I'm just wondering what to expect next?
The school is small and only has 1 class per year so moving classes isn't an option. I feel like I have been trying for ages and am failing at protecting her.
Sometimes after I've spoken to the school things improve for a while but before long it all starts again.
Please someone tell me what to do
