Children will learn to chew only if we teach them slowly by showing how to bite and swallow. It takes time.
She eats nothing because she doesn't know how to. Is she not gaining weight?? Does she not have teeth or did they come slowly?? Ragi Puri should be made slowly thicker and asked to bite... By showing how the parent does it..
Next Steps
Try to slowly give apple mashed or potato carrot boiled and cut into small pieces. which are soft and easily chewed. It's a slow process, don't worry.
