My 7 month baby started saying dada dada but after few days he stopped saying .now I’m trying him to say few words like dada ,papa I’m really worried what should I do .

A. Hai good afternoon !! Nothing to worry generally babies starts speaking 2-3 words mama,dada, Papa around 7-9 months can respond to our commands but sometimes they won't respond and utter words as they busy deviates very easily . If baby responding to his name and few commands, understanding expressions uttering words once a while then don't worry. Continue to speak and repeat words before words , gradually he will speak yet there is time. It takes 1.5 - 2.5 years for babies to speak.
