Event U Rox

My baby is 13 months now, she eats nothing. She is still on liquid diet ( milk) I have started giving her cow milk and it's digesting properly. But I know it's not sufficient she should have proper diet of solids now. Please help me what to do. I have shown her to the doctor his advice was don't offer her milk she will automatically demand for food and I have tried this also but nothing happened. She cried for milk only. Please reply and help me with this problem.
