I'm so worried about my 14 week old.
He appears in his own world. He does not look for contact from us. He stares at curtain poles, book shelves etc. He chooses these over faces but will give eye contact if you get in close. He does smile but it takes a lot of work to get a smile-tho he will grin at objects. He does not show interest in toys and does not reach out for anything. He does not respond to our voices. What do I do?
