yes, the 6th one is absolutely photoshoped. its a common shot, and there are you tube tutorial on how to composite the two images. in one, the parent is holding the head, and in another one, the barent is holding the hands in position. then the two are composited.
this style of newborn shot is usualy done during the first 9 days of life, where, once asleep, the baby can be manupulated. however, babies are very top heavy (head heavy) and it would be entirely too dangerour and irresponsible to shoot them without head support.
