My bby hs nt done poop from yesterday she s 11 month old..

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.

FM ko kitni der rkh skte hain agr baby nhi piya to..??
