My daughter aged 8 years, she stopped talking 3 days before. We asks everything about her favourite ones but he answering in silent. She playing games, watching television, but she cry when in deep sleep. I hope so, she was disturbed by mom and dad hard conversation last thursday. My mom said, on that time, she looks up yours conversations only. Also, my mother-in-law beated twice a times on that day. I think this would be give fear amount to her. But, I do not know what is the exact reason should be.
