my 2 yr old daughter is a smart energetic toddler, she speaks and comprehends just fine often she will scold you for something after she has been, but she doesnt ever change her behavior, she spits, bites, destroys things in the house from ripping curtains, to shredding paper, to smearing poop all over her room, to eating poop, she hits her 3 yr old sitter in the head with toys everyday, ive caught her sitting on top of her sister while shes sleeping hitting her... im concerned that she has signs of more than just the start of add, my brother had asburgers add adhd as a child and he didnt do any of these things, he grew up and is now a masters student, but never exhibited any of these... im a stay at home mom, my husband works 70 hrs a week, we have a great home, i do hands on projects with the kids everyday like preeschool i dont know what to do with her im at my wits end...
