I'm imagining his hair will be his Daddy's texture. His was slow growing as well...he was three before he had a full head of fuzz. By four he had lovely red ringlets. The baby has Mommy's eyes and her hair is a deep brown/black. But that face is a mirror of his Dad.
I'm imagining him having dark eyes, dark curly hair, with light skin. Big too, I don't know what he weighs now but like his Daddy he'll be off the growth charts soon. My Davey was taller than me at maybe ten years old.
