These pictures were taken by Dan Gueller of Philadelphia, who is specifically waiting for the moment when the children are asleep.Two-week baby after four hours of feeding and courtship fall asleep in any position. This is when Dan begins the shooting.He speaks of his models: “Newborn babies are very cute, and they can’t do anything by themselves. You can not ask the child to do something. So all you need is a lot of patience… Age is also important. It is best to take pictures of those who are younger than two weeks”.
