My son is 1.5yrs old. He only says few words like baba, dada.. is it normal ? when will start talking normally??

A. Hello ma’am This is normal talking only because a child can speak certain words by this age then that’s a good thing mostly by the age of 2 to 2 1/2 years a kid learn to say a lot of words that the child is listening around which are easy to pronounce so it’s perfectly fine need not worry about it
