A good night's sleep is as important to parents as it is to babies. Whether your child is still in swaddlers or running around at top speed for hours on end, a nice stretch of shuteye can do wonders for refueling his/her body -- and yours. But as for getting a kid to actually lay down for eight or so hours? Well, that's another story. Lullabytes is something of a smart soother for your iPhone, using simple controls, intelligent sensors, and sweet melodies to lull your child to sleep.
