Communication with others is facilitated by language. Speech and linguistic comprehension vary significantly from one another. All kinds of expression—verbal, written, visual, gestural, and facial—are considered to be part of language. While speech is a spoken language, it is thought to be the most essential and frequently used method of communication. As toddlers get older, their language skills get better. Since these changes will affect how children learn, parents should always pay attention to them. This can be achieved by setting a positive example, encouraging kids to study, and other strategies. Parents should constantly work to increase their children's potential in order for them to grow optimally as they are heavily accountable for the success of their learning. Present paper tries to study the theoretical aspects of childhood and language development. Advantage of language learning at early age and various theories of language development like nativism, behaviourilism and cognitivism are briefly explained.
