This person must have a genuine desire and love to give hugs, snuggles, have conversations with cooing and/or babbling babies, being silly to make the little ones smile and laugh and so much more happiness that comes along with caring for the innocent souls of infants. You also have to have a strong stomach for the less glamorous parts of being an infant caregiver - wiping the runny noses, cleaning spit up, changing diapers, etc.
