My sister (8F) doesn’t seem like a normal 8 year old to me at all. I must add that my parents for the most part are down to earth people and are understanding. She keeps doing they same things over and over again no matter how many times she is caught for doing something like:

Putting food she doesn’t want in her drawer (For some odd reason we have found cracked eggs in her shoe box too)

Opening ramen noodle packets and leaving uncooked noodles in her drawer or outside.

Putting water in my siblings pull ups and throwing them away.

Taking her tablet or my siblings tablets when explicitly told not to.

Putting marshmallows in the toilet

Putting Vaseline on windows when she puts too much on.

Stealing and using my mothers makeup and jewelry.

And the list goes on…She does all of this for no apparent reason. Whenever she is confronted most of the time she is quiet and says she doesnt know why she does what she does. Other times she says its because it’s because she never gets what she wants, but my parents always tell her that it’s because of the things she does, and instead of changing, she does the same things. Any advice?
