If the baby is healthy enough, there is absolutely no problem physically, then the child will listen to it. Then after that, the child will try to speak, then the child will go to school and would start reading and finally, the child would be able to write.
इस तरह से यदि बालक शारीरिक रूप से स्वस्थ है तो पहले सुनेगा और फिर बोलेगा, फिर जब स्कूल जाने लगेगा तब वहां पढ़ेगा और अंत में लिखेगा।
