my kid is 3 year 2 month old boy, he is telling everything related to studies, but he is not interacting with us like normal words pappa, mamma etc, may I know the reason please

A. hi are you giving screen exposure like tv ,mobile etc ? if yes then how much time ?? if its more than one hour ,you must decrease it To stay dependent on it for study of your child ,instead of it ,i suggest to read stroies , play different games with your child ,in not only increase his communication skills but help in better brain developement
