I'd assist in eventual object permanence (even though that's a
  lie), bonding and most CRITICALLY, _imprinting_, by holding the
  infant, patting him/her/it on the back, pulling the baby away
  from me so the baby can see my face.

  The best advice to give an infant?

  THIS IS WHAT A HUMAN LOOKS LIKE AND YOU ARE ONE OF US NOW.

  I communicate that by allowing the baby to study the 21
  dimensions of my face until the baby can mathematically figure
  out "this = face and it is good"
