When to Stop Using the SNOO

What is the SNOO, anyway? The name sounds straight out of the Grinch, right?

The SNOO Smart Sleeper Bassinet is a high-tech bassinet that was created to soothe newborns through naps and throughout the night using motion and sound. Babies are swaddled and gently “wiggled” throughout the night at different intensities based on their level of fussing.

When providing overnight newborn care in the homes of thousands of clients, many of them choose to utilize the SNOO as a tool. Whether you like the SNOO or hate it, it does come with an expiration date for use.

Is the SNOO Safe?

Most people say yes. The SNOO is FDA-cleared and designed to follow AAP safe sleep guidelines. For many families, it offers peace of mind that:

• Their baby is securely swaddled with nothing coming loose
• Their baby cannot physically roll onto their stomach
• The sleep surface is flat and firm

Some parents love knowing their newborn will wake up in the same position that they left them in the night before!

*Author note: In 2026, the FDA/AAP issued statements regarding the Extra-Small and Extra-Large sleep sacks that had not been tested to meet standards.

When to Stop Using the SNOO

This is one of the most searched questions online, and for good reason. Here are our recommendations as Newborn Care Specialists, Postpartum Doulas, and Sleep Consultants who want to balance safety with ensuring a lifetime of great sleep hygiene.

• Use any way you wish for the first 6 weeks
• Switch to Weaning Mode from 6–12 weeks
• Stop using the SNOO features [swaddle/movement] entirely once your baby is showing signs of rolling

Why? Movement plus restricted swaddling can become unsafe once rolling begins. At that stage, your baby needs more freedom of movement for their muscles to develop properly. You can still use the SNOO as a bassinet until your baby shows signs of starting to sit up.

What is Weaning Mode on the SNOO?

Weaning mode reduces constant motion. It only activates gentle movement when the baby actually cries. This prevents babies from becoming dependent on continuous rocking to stay asleep.

Weaning mode helps build sleep skills while still offering support.

The SNOO and Sleep Habits

The first 6 weeks we lovingly call the trenches. Survival mode. If something gives you one extra hour of sleep and it is safe, we say go for it.

But after 6–8 weeks, sleep habits start forming. [Meaning your baby remembers what happened yesterday and wants that repeated tonight and tomorrow.]

If your baby:

• Falls asleep only with motion
• Is rocked all night
• Never has a chance to settle independently

…you may end up needing sleep training later on. And we would rather help you build healthy sleep foundations early.

The Importance of Self-Soothing

One of my biggest concerns as a sleep consultant with the SNOO is that it intervenes immediately when a baby fusses. That interrupts the natural learning process.

Sometimes, babies just need a few seconds to:

• Wiggle
• Fuss lightly
• Reset
• Drift back to sleep on their own

Pausing before responding can make a huge difference in independent sleep skills. This is why our approach, The Sleep Steps, always begins with Step One: Pause. The pause can be adjusted to your baby’s age and temperament.

Signs It Is Time to Stop Using the SNOO IMMEDIATELY

Discontinue SNOO motion and swaddling if your baby:

• Is attempting to roll back-to-front
• Shows increased mobility

If these things are happening, you can continue to use the SNOO as a bassinet only, with no movement or swaddle.

Discontinue the SNOO as a bassinet entirely if your baby:

• Begins pushing up on hands or knees
• Begins showing signs of sitting up

When in doubt, transition early to be on the safe side.

SNOO vs. Night Nurse: Which Is Better?

This is such a big question that we wrote a whole blog about just that!

Is the SNOO Worth the Money?

That depends on many factors and from the parents that we work with that have purchased the SNOO, their answers vary.

If you are exhausted and want an extra hand, it can be a great tool. If you want an uninterrupted 15-minute shower. If you have other children that require your attention. Or if you could use any extra minutes overnight that the SNOO can try to soothe before you jump in. Then the SNOO might be a good investment for you! It’s not magic but some parents beleive that their babies slept significantly better in the SNOO than in their crib or bassinet.

However, it is expensive, and many parents don’t see a big enough change that it makes a difference. And of course, there are the possible long-term considerations.

There are also other similar products on the market to consider, like the Cradlewise Crib.

Long-Term Considerations

The SNOO’s swaddle restricts movement, which can have many developmental repercussions. It can delay rolling practice, limit small movements that strengthen muscles, and can reduce the chance to build sleep skills. There are many who believe that the risks outweigh the benefits. However, there are no direct studies showing that using the SNOO as intended has any lasting negative effects.

Final Verdict: Should You Use the SNOO?

Sure, but if you want to and always as a tool.

Remember:

• Use freely for 0–6 weeks.
• Use weaning mode for 6–12 weeks.
• Stop using the motion/swaddle once rolling emerges.

And if the SNOO isn’t getting you enough rest on it’s own, or if you’re worried about transitioning out of it later…We are here.
