Humidity and Temperature for Sleeping Babies and Children

Humidity and Temperature for Sleeping Babies and Children

Air conditioning can dry the humidity in the room, and babies and children can wake with a dry mouth and feel thirsty and their cries can equate to more nighttime feeding occurrences. Fixing humidity doesn’t mean they’ll have one less night feed – if they are hungry, then they absolutely need to be fed!

For children who are mouth breathers and sleep with their mouth open, a dry room can be an issue and sleep disrupter.

Humidity Range and Reasoning

A humidity range between 40-60% is healthy for the body, mainly because bacteria have a hard time growing in this range. The EPA’s recommends 30-50% for preventing mold growth in the house as higher humidity promotes mold growth. Some children’s hospitals keep their air at 55%. How a room is built and insulated is also a factor for promoting mold growth. If walls get cold at night, mold is more likely to grow.

Aim for a higher humidity level without mold growth. Factors include the season and construction of the room. You can get an inexpensive humidity thermometer or pick one up from your local hardware store.

The humidity level will be raised significantly if you aim a humidifier or diffuser at your child’s crib or, but the overall humidity of the room will not be as high. This is an effective way to give Baby the benefit of humidity while decreasing your risk of mold. However, you need to be sure Baby is warm if you’re using a cold mist.

Newborn Baby Sleep Temperature

If your child is an amazing newborn or beautiful older baby, the room should be between 68-72 degrees F.

It is very important that you not overheat your newborn when Baby sleeps as it increases the risk of SIDS/SUIDS. It has also been shown that using a fan can decrease the risk of SIDS/SUIDS by 72%!

Fans help with increasing the mix of the exhalation into the room air and improving room ventilation. This percentage is obviously very high and getting a small fan is worth the investment. In addition, you may want to invest in a fan guard, which is made out of fine mesh and fitted over the fan head to prevent little finger getting caught in the blades. This will also prevent your child from poking other objects in the blades. Place the fan away from Baby, ensure at least 3 to 4 feet between the tip of the ceiling fan blades and the edge of your child’s bed or other furniture, so if you have an older child who is tempted to jump on their bed or climb, they won’t reach the fan. A ceiling fan is ideal.

If the room is cooler for Baby, you need more layers. Layers do not equal blankets with babies! They can get intertwined and tangled in them and suffocate. More layers mean instead of just being swaddled in a diaper (which is very effective for a warm room), swaddle Baby in a onesie, or swaddle Baby wearing footie jammies. Or double swaddle! Or swaddle baby in a diaper alone with a velcro swaddle and a receiving blanket burrito-swaddled over it.

Overheating

No hat! At the hospital, the nurses will provide a hat for you… do not keep this on your baby while sleeping swaddled after the first couple of days..! In fact, full-term babies don’t really need a hat when dressed appropriately, even from birth. It’s really a strange American thing. If a nurse places a hat on your baby’s head right at birth, take it off! Smelling your baby’s head can trigger pheromones and increase oxytocin and help you birth your placenta!

Socks for sleep are also a no-no. Babies with cool extremities are not cold, and it helps them self-regulate their temperature while not wearing these. Socks and hats while sleeping swaddled can contribute to overheating and SIDS/SUIDS. You can check if your baby is too hot by feeling the back of their neck and upper back. If they’re clammy, they are too hot. If you’re warm, your baby is hot! If you’re hot, your baby is very hot! If you’re cold, they are probably perfect. Babies overheat faster than adults! Again, the ideal temperature for babies is 68-72 degrees F; this can be super cold for adults, but it’s super ideal for a sleeping baby, and some pediatricians even recommend the room be as low as 66 degrees F! Wow!

Why Swaddle Baby?

Swaddling is effective during the Fourth Trimester to help mimic the feeling of the womb. After wrapping Baby up in a blanket like a little burrito, Baby feels safe and secure because Baby feels boundaries, like when inutero. Baby is born with over 70 reflexes that Baby loses as Baby develops, and one is called the moro reflex or startle reflex. Swaddling helps Baby feel the boundary when disrupted by the reflex so that they have an easier time falling asleep and staying asleep. It can take up to 4 or 5 months for Baby to stop the startling, but you can stop swaddling after Baby starts rolling over and transition to a sleep sack.

Which Swaddles are Best?

We love the Ollie swaddle, which makes swaddling a breeze with velcro.


For quick layering advice, many mothers find “inception swaddling” or double swaddling super effective: first place Baby (wearing a diaper only) in a SwaddleMe or Happiest Baby Sleepea Swaddle, and then burrito-swaddle Baby in a muslin swaddle blanket such as a lightweight Aden + Anais muslin cotton receiving blanket.

Many of our clients love to double swaddle with the Miracle Blanket Swaddle and the Halo Swaddle for the second layer as well.

Toddler Sleep Temperature

It’s also proven that the ideal temperature for sleep is between 65-70 degrees Fahrenheit. If your child is a terrific toddler, dress them in a single layer of long pants and long sleeves. If the room is warm and it’s not a variable you can control, stick with short sleeves or nothing but a diaper.

Thirst Solutions Caused by Dry Air

As an adult, it’s easy to have a glass of water next to our beds when we wake thirsty. Obviously, this is dangerous for babies! However, toddlers can have a spill-proof cup near their bed such as the Munchkin 360 Training Cup. This cup is a great stepping stone for Little Ones transitioning from the bottle as it has a 360-degree drinking edge. Its spout-less design eliminates spills completely so if your child falls asleep with it in their hands or bed, you don’t need to worry about mattresses getting soaked as the cup automatically seals when your child stops drinking.

These are better to use than a straw-type of sippy cup for both developmental and sanitary reasons:

  • These cups are recommended by newborn care specialists, dentists, early intervention specialists, occupational therapists, and speech therapists.
  • They improve tongue, oral development, and in-turn, speech function as they help develop mouth muscles.
  • They’re easy to clean with no extra valves or parts.
  • The top piece, where your child’s mouth will touch, is silicone material; thus, it’s hypoallergenic since there are no open pores to harbor bacteria.

These cups also come in stainless steel if you want to keep it in the fridge for children who absolutely love cold water on hot days.

Buying the Best Humidifier or Diffuser

If you use air-conditioning or central heating, you may consider adding a humidifier to the room. A cool-mist diffuser/humidifier combo works really well.

Crane Humidifiers: Awesome and easy larger cool-mist humidifier. Don’t pour water into the doughnut hole. Everyone makes this mistake! Remember to tell your partner. You need to lift the clear top portion off, bring it to the sink, and fill it from the bottom by turning it upside down and unscrewing the cap.


Diffusers are another option to create humidity and can be used with essential oils. These diffusers require no filter for the essential oil. You just add a couple of drops of GMO-free pure essential oils which are calming and effective for sleep such as chamomile and lavender directly in the basin. Only use the red light setting because other lights have different wavelengths that inhibit melatonin and disrupt sleep. (Read more about Baby Night Lights and Better Sleep here.) You can also dim the brightness of the light and it has a cool-mist, doubling as a diffuser and humidifier. The waterless auto shut-off feature is a great safety net so when all the water evaporates, it shuts off.

Baby Night Lights for Better Sleep

Baby Night Lights For Better Sleep

Baby Night Lights

A quick Google search for “baby night lights” brings you to many magical and cute animal baby night lights and heart-shaped baby night lights but 99% of these baby night lights you see are proven to actually inhibit sleep.

If you’re using a nightlight in your baby’s/toddler’s/child’s room, or plan to, you need to know which type of lights to avoid so you can create the best possible sleep environment for your Little One.

If you already have a night light in your child’s room, and it’s something that emits a dim glow, it may be causing disruption to your child’s sleep, and here’s why:

The wavelength of different colors such as white, blue, and green-based lights inhibit melatonin at night. Melon-what? Trust me, your honeydew will love you for altering your child’s night light situation and your precious babe will be able to sleep longer and stay asleep at night.

Melatonin Magic and Sleep

The sweet sleep hormone, melatonin, is released by the brain when there is a response to light sensitivity in the eyes. This hormone is essential for children to fall asleep and stay asleep overnight. If the world wasn’t clogged with electric lighting, research has shown children fall into slumber between 7:30pm and 8pm.

It’s common for parents to choose cute nightlights that might emit blue, green, white, pink, or purple hues. Blue is especially calming and used by most manufacturers of baby night lights but it’s a scientifically proven sleep disrupter and mistake to use them if you’re sleep conditioning or sleep training, or trying to get your baby, toddler, or younger child to stay in bed or sleep well throughout the night.

Cell phones, laptops, TVs, and almost all home lighting have blue and white-based lights need to be off and out of the area where your child is sleeping or away from your child at least an hour before they sleep. This is because these lights inhibit the body’s secretion of melatonin by tricking the brain into believing it is still daylight.

What’s the Sleep Solution?

Red light is the only light, shown by research, that does not inhibit melatonin because red-based light has a much higher wavelength than white/blue/green light.

The goal is to use no light in the nursery initially. When parents or caregivers come into the nursery for night feedings and diaper changes, you can then switch on a night light that is a red night light. This solution is perfect as red light does not interfere with the chemical building blocks needed for sleep.

However, you need to plan the environment and timeframe leading up to bedtime. Think about the light your child is exposed to before bedtime if you are giving Baby a bath or brushing your older Baby or younger child’s teeth. Is your bathroom lit by regular white light or energy-saving lightbulbs? These emit much more blue light than old-style incandescent bulbs. If so, you may consider investing in a battery-operated light which is more appropriate for preparing for sleep in terms of helping the brain prepare for sleep.

Lights Used When Prepping for Bedtime

In the bathroom when brushing teeth or giving a bath, or in the nursery when dressing into pajamas, when first putting Baby down, or when reading a nighttime story (or two books) to your child, here are options:

Lumie Bedbug Light: A multi-purpose bedtime light which features a low blue light, while still producing a white/peach colored glow. Lumie Bedbug Light is non-inhibiting without having to use a red light in the room while reading or brushing teeth. This baby night light also includes a sunset mode option which gradually darkens the room, dimming after bedtime over a period of 15 minutes. This is perfect for toddlers and older children as well.

Battery-Operated Electric Candles are beautiful, glow like real candles, and create a calm, cozy environment for bedtime. These are my favorite electric candles as their flames actually move and dance. They transform your home into cozy-feel-goodness!

Don’t forget rechargeable battery chargers are a one-time, small investment and perfect for the bathroom in place of the main light at night, or reading area. Not only are you improving your child’s sleep, you’ll all wake less, and you’ll save money on your energy bill! Totally worth it.

Best Red Lights for My Baby’s Nursery or My Child’s Bedroom Nightlight

These are the top red baby night lights I recommend for parents when breastfeeding or bottle-feeding Baby throughout the night or when needing light to change Baby’s diapers during the night, or for your Big Boy or Big Girl when they get up in the middle of the night during potty-training:

Red Gummy Bear Baby Night Light: This red LED gummy bear light is cordless, portable, and squeezable to turn on/off. It has a sleep timer of 1-hour and is soft and durable.

Red Fairy Lights: Effective and adorable solution when used in a lockable Kilner jar as a portable baby nightlight.

Greenic 0.5W Plug-in Light Sensor LED Red Night Light: This 2-Pack Red Night Light is super cute and mini-sized, and very effective for hallways and bathrooms. It can be turned upside down to see less of the LED light. It’s bright enough but also dim enough for nighttime feedings, and quick wakeups for diaper changes or bathroom trips.

Hatch Baby Rest Night Light and White Noise Sound Machine: This red baby night light doubles as a white noise sound machine, which is another recommendation for parents as pure white noise (do not use intermittent ocean waves, water sounds, crickets, etc.) is scientifically proven to help babies and children’s brainwaves when waking to lull back to sleep and sleep deeper. This machine is remotely controlled with your smartphone, features a time-to-rise alert, and you can customize the brightness by dimming the red baby night light as well as by setting the programs to turn off and on automatically based on your family’s sleep schedule. During the day you can play with the other fun colors! It includes a toddler lock feature as well.

Other solutions for sleep include how cozy your Little One is, and how much humidity is in their room. Dryness can cause a thirsty baby or toddler. Read more on how to fix the humidity in your nursery and child’s room for better sleep.
