Hi. my son now 40months old he can hear will but only speaks few words like baba or mama. isit normal? thanks

No, he should have: A comprehensive assessment of his overall development including receptive ( comprehension) & expressive ( verbalizing ideas) language, non-verbal social communication social interaction, adaptive (self-help), problem-solving, & motor skills. It's important to seek speech/language therapy & other needed services at this time. I'll ask our panelist, dr.Mohammed aldosari to give you local resources.
