7 year old acting up..

I feel like my daughter has been feeling left out, and is doing stuff to get attention. I have had 3 babies back to back after her and she is my oldest. Lately she has been playing with her siblings and making them get hurt or puts the dog's chew toys in the snack bowl. Other than counseling what would be helpful. I tried talking to her and trying to understand what's going on but she just stays quiet. Any tips on how you mommies do it with multiple children would be helpful..
