Hello, can I hear stories that had more serious babies and what they are like now? I am very concerned because my 6mo rarely smiles or laughs. She'll smile at us when we come into the room but never to strangers and is NOT easily amused (just stares when we try to do funny things or will blow raspberries). She does make decently good eye contact. But I'm super concerned. Is 6mo past the point that it could just be "personality"? My friend called her "unapproachable" today, lol..
