Our children know us by sound and by sight when they are babies. Change something about your appearance and your child might try and keep you at arms length and could be very unsure of you. My daughter Emily never knew me without a mustache and needless to say, when I shaved it...she was not happy and kinda freaked out when she was 18 months old. The dad in this video had a very thick and full beard as he is holding his daughter. He tells her he has to go to the bathroom, puts her down and comes back out without the beard. She did not like it. See her reaction below....too funny.
