I, too am interested in the "adult hair". Max is 22 weeks old and he has such fluffy, full hair. He's like a little cotton ball at times but other times he looks like he just really scruffy. Should he get a big-boy haircut and get this taken down or do I need to wait until he is a little older? Both his mother and his father were silkier so I am wondering if this is something that comes with time.
