Tracy Raver, who describes her style as simple and casual, captures newborns while they are sleeping.
Swaddled in soft woollens or nestled in baskets, the tiny infants are photographed when they are just weeks old.
Baby face: Tracey Raver captures a newborn's expression as it dozes in a spotted woolly hat
The mother-of-one says: 'It’s all about timing and giving your child the freedom and space to be themselves.
'Favourites are layered outfits, bare feet, and babies in their birthday suits!
'My style is simple and clean, with the focus on those precious little faces. I like to catch all expressions... serious, smily, sassy and silly!'
And the expressions do not disappoint. One baby, sporting a spotted woolly hat, pouts in its sleep, while another smiles, as if enjoying a lovely dream.
Raver, who is based in Nebraska, runs her photography business with her sister Kelley, a mother-of-two. Together the pair run 'baby posing' workshops, teaching parents how to use natural light, and making the most of fabrics and props.
'We go over positioning on the beanbag, prop transitions, camera setings, use of natural light and techniques to keep the newborn calm and asleep,' says Kelley.
