my 16 months old baby not response whenever I call him only response on mobile sound plz suggest me what will I do I am worry for him. I don't understand whether he hearing my voice or not

A. If u r worried the easiest thing u can do is consult with your pediatrician and get a hearing test done for ur baby. It's a simple test and wouldn't take even a few minutes and won't hurt the baby. Also if the baby is speaking few words then u shouldn't worry he should be able to hear thats why he is able to speak.
