so we just go through colic and the dreaded 4 month sleep regression phase . when we move we baby to she own room around 3 month , we put a floor fan in there for white noise . she wall be right next to we tv room , she brother be next door and a loud 2 year old , and she big window be right on a busy street . and she be never a really good sleeper . while for some baby -lrb- lucky lucky parent -rrb- a sleep machine be all you need - for we we know it be just a stress-reliever for we , so that we would not have to worry that noise be interfere with she sleep . -lrb- we could tick that item off the list and move on . -rrb- the fan be just way too cold . so I purchase the sound machine -lrb- marpac 980a , see other review -rrb- and this sheep . I get this sheep for the car actually , as one other reviewer have mention it help they baby not scream in the carseat . after look at both -lrb- the marpac and the sheep -rrb- - the marpac end up in she room for consistent white noise all night , and the sheep go in the car . I do not want to worry that the timer function be the reason for poor sleep -lrb- ie when she wake up at night , she can not go back to sleep because the sheep be no longer on - tick another thing off the list ! -rrb- the sheep be really soft . unfortunately , the sheep do not keep she from scream in the car seat . however - it be great for I ! it be now in we bedroom , hang next to the bed - and it have be fantastic for I - as sleep deprive as I have be , it be often really hard for I to get back to sleep after get up to feed or tend to she or my son if he be sick and really need I in the middle of the night . have try muscle relaxation , all that other stuff that I usually do not need , but it would not work . have use a sound machine in the past -lrb- not the marpac -rrb- and hate it . the one I have try before all sound tinny or annoyingly inconsistent . the rain setting on this sheep , and the timer be perfect for I - have no trouble fall back to sleep at any time . thank you sleep sheep !!!!!!!
