We're about to renew Little Elephant's passport from when he was 4 months old. He doesn't really look like that anymore. I'm fully expecting to get an RFID passport.
Hints on passport photos for infants: Put background sheet on conveniently low horizontal surface (bed, floor, etc.). Lay subject on sheet, face up. Take photo straight down, preferably while assistant makes wacky noises/faces next to camera.
