I see a lot on this site and all over the Internet about toddlers that are late to talk. The general consensus seems to be as long as they can understand when you talk to them then don't worry, they will talk when they are ready.
Well my child does not understand anything you say to him. He is 22 months old and doesn't seem to even understand when you call his own name. He doesn't appear to have any hearing problem either (Sometimes he turns to me when I whisper to him from across the room, but is just responding to the sound, and doesn't comprehend what I am saying). He seems to have his "own" language and is always talking/babbling but not saying any words. The fact that he doesn't understand anything we say is very worrisome.
He seems to have very good visual communication though, he knows when I put my shoes on it is time to leave and starts trying to open the front door. When I carry him to his room he knows its time for bed (because he doesn't like to go to bed and starts throwing a fit before I even get to his door.) He points to things he wants and if you reach your arms to him (even from across the room) he will come to you. Sometimes if he does something physical (eg: tumble down, pick his nose, put blocks together) if you respond by laughing/getting excited, he does it again and again to entertain you.
So the combination of very good non verbal communication but complete lack of verbal communication has me quite confused. Is this a sign of something?
// EDIT: an update note from the original author, dated June, 8th
I took my son to the dr. today and she said he should definitely be able to understand simple commands like "Give me" or "Come here" and since he cannot understand any verbal command, it is a cause for concern.
She gave me a number for early intervention so I can get him evaluated and get to the bottom of any underlying issue
