This is quite a common habit in children and as with all habits at this age is hard to stop once it starts.The primary aim should be to get your daughter's sores healed up so she has nothing to scratch and nothing that is itchy.From your description I am concerned that your daughter may have infected sores caused by her scratching and picking at them.It would be best to ask your doctor to see her just to be sure that she does not need an antibiotic to help to clear up the infection and help the sores to heal.The doctor will also probably precribe an ointment called Bactroban to help to heal these sores.
