#AskTheExpert My baby started babbling-making noises like 'coo', 'gaga', 'oooh' and 'mmm'- at 3 months. He used to make these sounds throughout the day. Now at 5 months, he had drastically reduced making such sounds. Hardly once a day I can hear such sounds from him. This has especially started after I started feeding him small quantities of solid food ( as per doctor's recommendation ) Is this normal ? how can I encourage him to make more sounds?
