My son looks a lot like me. He has my eyes and seems to have the build from my side of the family. When he was born he had a pile of red hair just like my DH. That all fell out and his hair came in the color of mine. He does still have some reddish undertones in it if he's been in the sun.
My Dad always said (referring to infidelity) " Babies have to look like their Daddy at birth, otherwise they get left on mountain tops!"
