How to Put a Baby to Sleep in 40 Seconds? [Follow these 4 Steps]

Putting a baby to sleep quickly and easily is the dream of most new parents. While it’s not always possible to get a baby to sleep in just 40 seconds, there are techniques and tricks you can use to help your little one fall asleep fast and stay asleep longer. With some practice, you’ll be able to master the skill of swift and soothing bedtime.

Why a Quick Bedtime is Helpful

Getting your baby to fall asleep quickly at bedtime is beneficial for several reasons:

  • It helps establish a consistent bedtime routine which babies thrive on.
  • It prevents baby from getting overtired which can cause sleep issues.
  • It allows you more time to yourself in the evenings.
  • It ensures baby gets the sleep they need for healthy development.

Establishing a quick and soothing bedtime routine early on encourages good sleep habits right from the start.

How Does the 40 Second Method Work?

The key to this super-fast sleep strategy is following your baby’s natural sleep cues and intervening at just the right moment. Here’s the science behind how 40 Second Method works:

There are five stages of sleep that we cycle through at night. Stage 1 is light sleep where your baby is drifting off. During Stages 2 and 3, they enter deeper sleep. Stage 4 is REM sleep where dreams occur. Newborns spend about 50% of their sleep time in REM. The final stage is wakefulness as sleep cycles complete.

Ideally, you want to put your baby down to sleep at the start of a sleep cycle. This is right at the transition from wakefulness to light sleep before they enter those deeper sleep stages. The 40-second method aims to identify that prime moment so you can set your baby in their crib before deep sleep kicks in. That way, they don’t fully wake when being put down.

Timing is critical. You have just a short window where your baby is starting to show sleep cues but not yet in a deep sleep state. Intervene too soon and you’ll disrupt the process. Wait too long and you’ll miss that ideal window and have an overtired baby who struggles to settle.

But don’t worry, there are some clear signs to look for that indicate your baby is ready for sleep!

Step 1: Watch for Baby’s Sleep Cues

The first step in successfully putting your baby to sleep in 40 seconds or less is observing their behavior for signs they are ready to drift off. Here are some key sleep cues to look for:

  • Slowing eyes movements: Your baby’s eyes will begin moving more slowly and blinking frequently as sleep approaches. Their pupils will also dilate.
  • Decreased activity level: Your once active baby will start moving less as their energy winds down.
  • Loss of interest: A awake and alert baby will abruptly lose interest in their surroundings and toys when getting tired.
  • Rubbing eyes and ears: Babies instinctively rub their eyes and pull their ears when getting drowsy.
  • Sucking motion: Many babies suck on their lips, fingers, or clothing as they start to nod off.
  • Fussiness: You may notice your baby getting fussy, cranky or upset as they grow overtired. This is often a big sleep cue.
  • Yawning: Frequent big yawns are an obvious sign your baby is ready for sleep.

Once you see 2 or more of these sleep cues, it’s prime time to try the 40 second method. Timing is important, so don’t wait too long!

Step 2: Create the Right Sleep Environment

Once you recognize your baby is ready for sleep, the next key step is quickly creating an optimal sleep environment. This allows your baby to drift off as easily as possible in those 40 seconds while also setting the stage for uninterrupted slumber. Follow these tips:

  • Lower lights: Dim the lights in the bedroom to start promoting sleepiness. Close curtains and blinds as well.
  • Reduce noises: Turn off loud music, TVs and devices. Try using a white noise machine to block disruptive household sounds.
  • Crank up the cool: Lower the thermostat to around 65-70 degrees F which mimics your baby’s womb environment.
  • Wrapping warmth: Swaddle your baby in a blanket to keep them cozy and comfortable as they fall asleep.
  • Rock on: Have a rocking chair ready next to the crib for rocking your baby during the 40 second process. The motion soothes babies and stimulates sleep.

Having a peaceful, dark room at an ideal temperature sets you up for success. Just don’t forget to place your baby in their crib once asleep!

Step 3: Calm and Soothe Your Baby

At this point, you have a sleepy baby and a relaxing sleep space. Now it’s time for the final step of using calming techniques just before placing them in the crib. The goal is to help them fully unwind so they transition seamlessly into slumber.

Here are proven methods to soothe your little one in those critical 40 seconds:

  • Rocking: Gently rock your baby in your arms or a rocking chair. This rhythmic motion is extremely soothing for infants.
  • Shushing: Make a soft “shhh” sound near your baby’s ear to replicate sounds from the womb.
  • Patting: Gently pat or rub your baby’s back or chest in a repetitive, calming motion.
  • Singing: Quietly sing a lullaby or soothing song to help them unwind.
  • Swinging: Letting your baby swing gently back and forth can induce sleep. Use an infant swing if needed.
  • Sucking: Let your baby suck on a pacifier or your pinky finger to satisfy the sucking reflex.
  • Riding: If your baby fights sleep in your arms, try putting them in a stroller or car seat and moving around.

The key is finding the right method or combination that works best for your unique baby in that moment. With practice, you’ll figure out how to quickly and effectively soothe them to sleep in under a minute.

Step 4: Put Your Baby in Their Crib

Here is comes – the big moment to put your sleepy baby in their crib! After following the first three steps, your baby should be primed for a seamless transition into their bed. To boost success:

  • Slowly stand: From a seated position, rise very slowly and gently while swaying. Avoid any abrupt movements.
  • Keep calming: Continue your shushing, patting, or rocking as you move towards the crib for a smooth hand-off.
  • Watch the head: Carefully place your baby on their back while cradling their head and neck for support.
  • Limit eye contact: Avoid prolonged eye contact which stimulates wakefulness.
  • Sneak away: Quietly back out of the room once they are settled in the crib.

Your baby may fuss for a moment as they adjust to the new environment. But stay strong and don’t race to immediately pick them up. If you executed the prior steps well, they should soon drift off to sleep.

And just like that, your baby is down for the night in 40 seconds or less! It takes some coordination and finesse but can be done.

Troubleshooting the 40-Second Method

This rapid sleep strategy won’t work like a charm every time. Here are some common hurdles and how to overcome these problems:

Problem: Your baby starts crying as soon as you put them down.

Solution: You likely missed the sleep window so wait a few more minutes for deeper sleep cues next time. Gently pat or shush them until settled.

Problem: Your baby keeps waking up shortly after you put them down.

Solution: Try swaddling them or letting them sleep in a swing for naps. The confinement and motion can help extend sleep.

Problem: Your baby fights sleep and gets worked up.

Solution: If soothing isn’t working, take a short break before trying again. Overtired babies have more trouble unwinding.

Don’t get discouraged! Even if your baby doesn’t immediately conk out in 40 seconds, regularly using this routine can help reduce bedtime battles.

Establish a Soothing Bedtime Routine

While the 40 second method may help during naps or occasional bedtimes, you’ll also want to develop a consistent evening routine. A predictable series of self-soothing activities leading up to bedtime will relax your baby and cue their body for sleep. Try incorporating:

  • A warm bath with lights dimmed
  • Gentle massage with lavender lotion
  • Rocking or swinging with a lullaby
  • Reading a bedtime story in a hushed tone
  • Keeping lights low during final feeding
  • Maintaining a quiet environment

Following the same sequence of peaceful activities will get your baby ready for sleep. Then you can turn to the quick 40 second routine for helping them fully unwind in the crib.

FAQs About Putting Baby to Sleep in 40 Seconds

Is it bad to let my baby cry themselves to sleep?

It’s best not to let a baby under 6 months cry it out to sleep. Responding to their needs and using calming techniques helps form a secure attachment. After 6 months, some short fussing can be okay if needed to settle.

Where should my baby sleep – crib or family bed?

The AAP recommends room-sharing with your baby but not bed-sharing in the first 6 months. Use a firm, bare crib or bassinet next to your bed. This reduces SIDS risk while keeping baby close.

How do I know if my baby is overtired?

Signs of overtiredness include crying, fussing, difficulty settling, rubbing eyes, jitteriness, and disrupted sleep. Try catching your baby earlier in their tired cues.

What if my baby wakes up soon after falling asleep?

Frequent waking can mean baby isn’t tired enough. Make sure to use the sleep window method. Check that the room is dark, cool and quiet too.

Should I let my baby nap longer if they slept poorly at night?

Yes, compensating with longer or extra naps can help overtired babies recover after a bad night’s sleep. Watch for sleepy cues to time good nap periods.

Using the 40 second method takes some patience and practice. But it can transform bedtimes for both you and your little one. Tap into your baby’s natural sleep rhythms and try these soothing steps to rest easy and dream big. Pleasant dreams!
