Question for you all as I believe most of you already have kids. My nephew is 2 yrs old in 2 weeks and he is completely non-verbal. Not even sounds that we can't understand, no sounds at all. He just points at everything. He understands everything though and when he cries he makes noise, so I don't think it's a hearing issue.
The parents don't seem concerned at all. I personally would at least ask someone professional about it if it were me. But they also don't do much early education. They don't read to him or anything like that really.
On a side note, I've noticed ever since he was little that he has a lot of autistic tendencies. He's very OCD about things (if a door is open, he freaks until someone closes it. Same with things (i.e. spills or messes or keys, etc) on the ground, he will whine and point at it until someone picks it up.
They used to live in a small town of 500 people but just moved close to us. Should I gently mention to them they may want to have it investigated?
