<s>[INST] My 7 year old niece likes to eat graphite. She said she s been doing it since she was 4 years old. I asked her if she was wanting something chewy or crunchy to chew on and she said no. She doesn t use mechanical pencils for school. What are positive ways to get her to stop. I don t want to tell her mom because her mom will get after her negatively. [/INST] dear user, thanks for your query.your child have unusual feeding habbit called PICA.it may be due to stress or vitamin or minerals deficiency or due to lake of care at home.i suggest you to give her multivitamin and iron supplement and encourage her to leave this habit. </s>
