Hi I am a Flower Essence therapist from near cambridge (UK).
There is a lady in Irleand called Ann Callaghan who makes "Indigo " essences for children. They are very effective. She will also make up a bottle for you and post it out.
She would only need to speak to you by telephone to help you with a bespoke essence.
I have had two children with similar issues. Look at Jan Tober "Indigo Children".
