MEET SNOO
The other new member of your family!
Congratulations! And, thank you so much for choosing SNOO Smart Sleeper®
to help your baby—and you—during these amazing first 6 months!
Designed by celebrated pediatrician Dr. Harvey Karp, SNOO is a totally new
type of bed that will help your baby be rested, healthy and happy.
What’s SNOO’s secret?
• It’s the only bed that perfectly mimics the rumbly sound + gentle
rocking babies love in the womb.
• It “hears” your baby’s cry and automatically responds with increasing
levels of soothing white noise + jiggly motion…often calming fussing in
under a minute.
• It’s the safest bed ever made. It oers you extra peace of mind by
keeping your baby safely on the back—all night long.* (Stomach
sleeping is associated with a higher risk of infant sleep death.)
*When used as directed.

SNOO AND YOUR BABY
The first 6 months.
Whenever you need a break—to fix a meal, take a shower or get some sleep—
SNOO will be your faithful helper, ready to assist you 24 hours a day…7 days a
week…month after month!
Within just days, SNOO will help your baby*:
• Fall asleep faster.
• Sleep longer.
• Cry less—and calm more quickly.
But, that’s just the start of SNOO’s benefits!
By 2-3 months, SNOO helps even more:
• Adds 1-2+ hours to your baby’s sleep.
• Prevents risky rolling to the stomach.
• Gives your baby all the benefits of swaddling—without the risks.
By 3-6 months, SNOO perfects your baby’s sleep:
• Boosts sleep even through growth spurts, colds and sleep regressions.
That’s important because these troubles often cause babies to
start waking every 2 hours—all over again.
• Sleep trains your baby naturally—without the need to “cry it out!”
• SNOO’s weaning feature makes it easy to transition to a crib.
*Infants over 6 weeks old may take 3-7 days to adjust and show improved sleep.

• Lay the dust bag that SNOO came in on the floor. Now, place the bed
upside down—on top of the bag.
• Snap each leg into the base. Be sure to line up the arrows on each leg
bracket with the same colored arrows on the base.
• Screw each knob in—all the way.

THE SNOO APP
Makes SNOO perfect for your unique baby!
Download the App today! Here are App features parents love the most:
Remote Control – Lets you adjust SNOO from your bed…or anywhere.
Change SNOO’s levels from your mobile device. Monitor your baby’s sleep when
you’re not at home!
Level Lock – Improves sleep if your baby is waking too often.
Many of us get sleepy on the train. Well, more rocking + sound can also boost
baby sleep…even through growth spurts and sleep regressions. Locking keeps
the bed’s sound + motion fixed (won’t rise with crying...or slow with sleep).
Motion Limiter – For babies—or parents—who like less jiggle.
This blocks the fast speeds, but still allows stronger sound in response to your
baby’s fussing.
Response – Lets you make SNOO more—or less—sensitive to your baby’s cries.
This makes SNOO react faster to soft cries…or slower if your baby is a noisy
breather and grunts a lot during sleep.
Preemie – Gives gentler rocking to tiny babies.
This blocks the fast speeds until your baby reaches the due date. (If you feel your
preemie needs extra motion, just toggle this setting o.)
Weaning – When you want to prepare your baby to transition to the crib.
Provides gentle sound—but no motion—all night. SNOO will still respond to your
baby’s fussing with sound + motion. Select this option 1-2 weeks before you plan
to move your baby to the crib, usually around 6 months.

• Unzip the sack and spread open the inner bands.
• Lay your baby on the sack. Be sure to place the shoulders 2-3”
higher than the top of the sack.
• Straighten the arms…pull the inner bands around and attach them very
snugly. (The bottom edge of the bands should cover most of the hands.)
• Pull the fabric at the top up and over the shoulders and zip the sack
completely. (The top of the zipper should be below your child’s chin.)
ALMOST READY
Becoming a master swaddler!
The SNOO Sack is the safest, easiest swaddle ever made! It attaches to special
clips on SNOO to keep your baby safely on the back…and reduce risky rolling.

USING SNOO
Let the fun begin!
Now that your bed and App are set up and your baby is snug, we suggest giving
a nice feeding—and a good burping—to prepare your baby to SNOO-ze!
Place your baby in SNOO
• Lay your baby down, placing the feet at the end near the Activity button.
• Slide each elastic loop—on the SNOO Sack safety wings—all the way
onto its own safety clip.
15
Note: For the first weeks, we suggest you put your little one down drowsy or fully
asleep for naps and nights. As SNOO’s natural womb rhythms become familiar,
they will help your baby learn to fall asleep in SNOO.

16 17
Turn SNOO o
To stop SNOO, just push the Activity button once or slip a loop of the swaddle
wing o a safety clip.
For extra guidance, visit our step-by-step tutorials at happiestbaby.com/faq
Turn SNOO on
Push the Activity button once. The light will turn blue, and SNOO will start gently
rocking and shushing your baby.
Note: If you push the button without slipping the loops onto the clips, the bed
won’t turn on and the button will blink white.
Let SNOO work
SNOO will gently rock and shush your baby for all naps and all nights. And, when
it “hears” crying, it responds automatically—to soothe the fussing—by moving
through one or more levels of increasing white noise + motion.
Each level increase is indicated by a change in color of the SNOO Activity button:
Blue > Purple > Green > Yellow > Pink.
Blue is like gently rocking your baby in your arms.
Purple is like driving around your neighborhood.
Green is like taking a fast hike with your baby in a sling.
Yellow is like quickly bouncing on a yoga ball.
Pink is like a jiggly subway ride or driving with your baby on a bumpy road.
Once your child is calmed, SNOO will slowly reduce the vigor of its sensations
until it returns to the gentle blue baseline level.
If the fussing lasts for more than a minute, just pick your baby up for a feeding,
diaper change or cuddle. (If crying continues for a couple of minutes, SNOO
will automatically stop and the Activity button will turn red.)
NOTE: If the Activity button is blinking white, please check that the loops of the
swaddle wings are engaged correctly.

DR. KARP’S TIPS
Great advice for great SNOO-zing!
To create SNOO, Dr. Karp worked with hundreds of families to find the best levels
of sound + motion that quickly calm fussy babies and boost sleep. Through this
research, he developed a collection of eective, science-based tips.
Here are a few of his thoughts and suggestions:
Babies can be put down in SNOO asleep…or awake.
In the first weeks, you can lay your baby down either drowsy or asleep. As she
gets used to SNOO, the natural womb sensations will help her learn to self-
soothe and make it easy to put her down awake.
Use SNOO for nights and naps.
The more times babies sleep in SNOO, the faster they associate its gentle
rhythms with bedtime…and the sooner they become great sleepers!
SNOO mimics the calming rhythms we use when cradling babies in our arms.
When we hold fussy babies, we naturally rock a bit faster and shush louder
to settle them. We slow down—and quiet down—once they’re asleep.
Similarly, you can calm your baby’s fussing faster by boosting SNOO’s level by
pressing and holding the Activity button for 5 seconds or using the App.
Feeding more in the day helps babies need less milk at night.
Newborns feed 8-10 times a day…including every 2-3 hours at night! However,
giving a few more daytime ounces can help your baby sleep an extra hour or
more at night. Consider waking your baby from naps that last over 2 hours to
give a meal and also consider oering some cluster feedings in the early evening
and a dream feed at night.

22 23
Swaddling snugly with the arms down is the key for great sleep!
Although some babies resist wrapping, arms-down swaddling helps most sleep
better. If your baby’s arms pop out from the inner band of the SNOO Sack, check
that it’s snug and that the lower edge covers most of the hands. Locking SNOO
on a higher level may also help your child be more accepting of the swaddle.
Pick up your baby if SNOO doesn’t quickly calm crying.
SNOO responds quickly to crying, often calming fussing within 30-60 seconds.
However, if the upset lasts longer, it’s unlikely that SNOO will succeed. So, if
crying continues, you should pick up your baby. It’s the signal she needs…you!
Don’t worry about vomiting or acid reflux in SNOO.
Spitting up (acid reflux) is common, but babies naturally turn the head when it
happens…so there’s very little concern. If your doctor wants you to raise your
baby’s head to reduce reflux, our SNOO Leg Lifters are perfect for that!
Embrace the jiggle!
Some parents find it very odd to see their baby jiggling on SNOO’s top levels.
But, many babies love vigorous bouncing on exercise balls and going on bumpy
car rides. Jiggling often quickly calms crying during the early months because it
mimics the motion babies love in the womb!
By 3-4 months, babies become more alert…and this can undermine sleep.
For babies who suddenly go through a 3- or 4-month sleep regression, locking
SNOO at a higher level can help tune out distractions and keep them sleeping.
After weaning from SNOO…use white noise for at least a year.
Sound eases the transition to the crib…and helps babies stay good sleepers.
Your baby is unique! It’s easy to customize SNOO so it’s perfect for your baby.

CARING FOR SNOO
Cleaning SNOO
For safety reasons, the SNOO mesh is not removable. However, you can easily
spot clean SNOO using a soft cloth with warm water and mild soap. At one end
of the bed, there is a zipper to allow you access to clean between the inner and
outer mesh walls. Note: Never use bleach or abrasive cleaners.
Cleaning the mattress
The mattress has a water-resistant cover to prevent stains and contamination.
You can gently clean the mattress cover with a soft cloth with warm water and
mild soap. Then, air dry thoroughly—before using the mattress again.
Cleaning SNOO Sacks and sheets
Machine wash with similar colored laundry in warm or cold water. Never use hot
water or chlorine bleach. Tumble dry on a low heat setting. Note: When washing
the SNOO Sack. Make sure the Velcro wings are attached to each other and/or
zip the sack closed to avoid damage caused by the Velcro clinging to other items
in load. Also, give extra dryer time on low heat to completely dry the sack.

Dear Friends,
I am so happy to introduce you to…SNOO!
In recent years, almost every product we use has been improved, except baby beds.
Amazingly, cribs and bassinets have been unchanged…for over 1000 years! They’re
pretty much just flat, still “boxes” to protect babies from falls and the family dog.
That’s why we created SNOO!
In the womb, babies are cuddled, shushed and rocked…24/7. That’s why infants don’t
sleep well flat on the back, in still beds, in quiet rooms. And, frequent waking leads to
the #1 parent stress: exhaustion! Bone-weary parents more easily fall victim to nursing
struggles, mastitis, marital fights, accidents, anxiety, depression and trouble losing the
baby weight. Tired adults also bed share more, which leads to 1000’s of infant deaths.
And, today’s parents have it harder than ever because they often have little or no
support. Think that’s normal? Think again! Moms throughout history always had 3-4
“nannies” to help them (their mom, grandma, cousin, etc.).
Weaving together ancient wisdom and top science, SNOO boosts sleep with a
perfect 4th trimester of gentle sensations. Plus, it keeps babies safely on the back, all
night.
Bottom line: Babies deserve safer, better sleep…and so do tired parents.
With SNOO, babies are a whole lot easier to figure out. If SNOO quickly soothes
crying, keep your head back on the pillow—your job is done! And, if fussing lasts
over a minute, you know your baby needs YOU…for milk or maybe just a snuggle.
Thanks for letting SNOO help you help your baby during this very special time of life.
