1) It can feel and hear your baby fussing and will automatically start gently jiggling and playing white noise to sooth your baby back to sleep (of course if baby is hungry or just needs some loving arms, he'll keep crying and you'll come to the rescue, but the idea is that the "smart" bassinet will save parents from a good amount of lost sleep when a fussy baby simply needs a little jiggle to get back to sleep).
2) It comes with 3 sizes of breathable swaddles (which we know are fabulous for soothing babies) that are safe for baby's hips, and also hook right onto the bassinet to prevent baby from rolling over into a dangerous position! YES!!!!
3) It was developed with curious/mischievous older siblings in mind, so it is incredibly stable. I gave it a good yank from the top and it did not budge.
4) They have a 30-day return policy with free shipping both ways, meaning you can try it out risk free. But come on, I can't imagine anyone needing to send this back. My only concern would be how to wean the baby from SNOO to regular crib at 6 months. But I'm sure Dr. Karp and the Happiest Baby team have some good suggestions for a gradual and painless transition!
*I just want to throw in here that babies should NEVER be left to sleep unattended in a car seat, as they can quickly get into a position that compromises their airway.
