When DH dropped DD off at daycare this morning, they advised him that they've been having problems with DD lately.
She's been picking fights with other kids and hitting, biting and kicking them. She also screems a lot.

I've started noticing her having a violent temper as well in the past month - like when she gets told off at home, she retaliates by trying to grab my hand and bite it and her facial expression is visably angry. She has even tried to strangle me.

She'll be 3 in March...where has my angel gone?
What can I do?
