These cute newborn babies just can't be bothered having their pictures taken... all they want is a nice big snooze.
The adorable images were taken by Philadelphia photographer Dan Cueller who waits until the very moment the babies drop off to sleep to capture the perfect picture.
At just two-weeks-old the pampered tots must 'endure' up to four hours of feeding and cuddling to reach just the right level of sleepiness to doze off and be perfectly posed for the cutest of pictures.
He said: 'Newborns are naturally cute and they can't really do much at this age.
'You can't just ask a baby to do something, so it's usually best and easier to pose them when they are asleep.
'The trick to photographing newborns is really just waiting, keeping them warm and full
'We always have several hands near-by just outside of the frame.
'And if the baby is even slightly awake we won't do it until they are in a deep sleep.'
Since Dan began his new profession, charging $350 (£220) per portrait session, his business has been baby-booming.
