I have a 5 week old preemie who is not the easiest baby at all. He literally cried 90% of the time hes awake and its impossible to put him to sleep without nursing! My sis in law told me about this app and it seems to be the only thing that can get him to sleep without me nursing. Also if he is fussy I turn on the hairdryer or vaccum sound and give him a pacifier and hes immediately calm.
