Lulu i dont know alot about it but i will try find out for you. I know someone who has had similar issues with there toddler and she took her to a naturopath, i am not sure of the specifics but i know the child was lacking in something and also had other issues. Anyway she now has i think it is like a calming/relaxing syrup (mixes in yoghurt) that is given an hour before bed. I know there are other things the family changed also but as i said i am not sure of specifics, i will do my best to find out asap and get back to you.
