7 year old

Lisa • Mother of three. Had first child when 19. She had a heart defect and other birth defects but is doing great now. Then had cayden two and half years later and finally my baby boy Skylar 2 years later.
Help!! My 7 year old daughter won't stop acting like an animal. A dog most days. She barely wants to walk unless on all four. Barks alot, catch her eating and drinking like a dog.... she won't stop no matter what I do...is this something to be worried about or am I worrying for nothing
