My baby girl is 1 year and 8 month she is short tempered and arrogant, she will not give her favourite things to anyone, she beats beats her elders when they are scolding her, and when she's angry she will lay down on the floor and cry. She speaks a lots of words, that's closer to 40 and she tells her name when we ask her. If v r letting her to do what she likes she's happy and loving. On her good moods she always smiles and always happy. Is she hyperactivity.
