Hi V.,
I live in Yonkers, if rthat helps you. I have a two year old daughter. I think that what the other moms are saying is true; that each kid develops at their own rate and it only causes you more worry if you compare them. Often, when kids are the youngest, like your 18 month old, the older siblings are doing the talking for him. What Cher said to do was great; have him respond with words! If he continues to struggle, then maybe talk to your pediatrician about referring him for a speech evaluation.
