My niece is 8 years old. An average, shy student. Trinity has a habit of chewing on almost anything and everything. From her clothes to her toys. None of her barbies have feet. She destroys everything we give her. She also has on numerous times cut her hair down to the scalp. She is very impulsive, but always remorseful.. She has a few friends, although they say she is very "bossy". I must add that she is currently on medication for ADHD. She sees a couselor every few months, without any benefits , that I can tell. She is a lovely, respectful child. My brother is at his wits end. What can you advise?.
