Not making eye contact?

Lacey
My 10 week old doesn't seem to be making consistent eye contact. Sometimes I swear she's looking right at me and other times she refuses to look at me. She does smile when you say her name in an excited tone but still won't look at you. Anyone else have a 10 week old without consistent eye contact? My 3yo seemed to make contact way sooner than her sister. Also, I made the mistake of googling it and all kinds of autism articles are coming up. She has a doc appt Thurs but just figured I'd ask here too!
