Caring for Your Smart Sock 2 and Avoiding Red Marks
June 4, 2021
Proper care of your Smart Sock 2 will result in the best user experience. Below are some tips on caring for your Smart Sock 2 including cleanings and how to avoid red marks. Learn about how to select the correct size, check the fit, and more here.
Proper Care for the Fabric Sock
We recommend washing the fabric sock at least once a week. After removing the Smart Sock electronics, use cold water to hand-wash the fabric sock or machine wash the fabric sock in a garment bag on delicate cycle.
Allow the fabric sock to air dry completely before the next use. Avoid placing the sock in the dryer as the heat can possibly deform the vinyl window and cause the fabric to lose its shape faster. Learn more here.
Long-term Use of the Fabric Sock
The fabric sock will naturally wear over time. If you are planning on using the Smart Sock 2 for future children, we recommend purchasing a new set of fabric socks with every child. Find replacement socks on our website.
Sock or Sensor Discolored?
We see discolorations on Smart Sock sensors from time to time. It can be an issue of the natural oils in the skin or just plain old dirt. Plastic is already a very porous material and likes to trap anything it can get. The fact that the sensor is white only magnifies this issue.
If you notice any discoloration, simply wipe the sensor with a baby wipe or an alcohol pad. Make sure it’s completely dry before charging or placing it on your little one.
What Causes Red Marks and How Do I Avoid Them?
Your baby’s well-being is our top priority and we know it’s yours, too. We are committed to the quality of our product, and as parents ourselves that use the product with our own children, we stand by it.
Newborn skin is soft, sensitive and can be quite hydrated. The plastic sensor window inside the Smart Sock is in an area that doesn’t breath well, since plastic doesn’t wick away moisture like fabric. If the Sock is on one foot throughout the night, it is possible for newborns to develop a “water bubble” in that area. Fortunately, these are very superficial and typically reabsorb during the day.
To prevent this, we recommend rotating the sock around every 4 hours during use until around 1 month of age to give the skin a chance to dry out more.
Red marks from the Owlet Smart Sock are not a common occurrence. The small number of users who notice red marks on their baby’s foot after using the Smart Sock have found that the Sock was on too tight or they were using the wrong size fabric sock. The Smart Sock is similar to when a baby shoe is too tight or too small and leads to discomfort for the child or the potential for pressure marks. Our research, in partnership with dermatologists and pediatricians, shows that these rarely occurring marks are not burns.
These red marks may appear on the top of the right foot or the bottom of the left foot.
Pressure marks can be caused in a few different ways. Contributing factors include: pressure from over tightening the Sock, a fabric sock size that is too small, your baby laying on top of the sensor when sleeping on their stomach (with the Smart Sock on the right foot), or Baby standing on the Smart Sock too long (on the bottom on the left foot).
If I noticed a red mark, what should I do?
Check the Sock Size
Try going up a fabric sock size or loosening the straps on the fabric socks to make sure they are lying flat without any ripples or puckers. Ensure the straps are lined up so that the sensor stays straight up and down. This will help the windows line up.
Switch it Up
Rotate the Smart Sock between feet to prevent too much pressure being on the skin for too long.
These rare marks can be found on the top or bottom of the foot near the pinky toe where the plastic windows in the fabric sock lie and can be caused by a few different reasons: pressure, moisture, and friction.
Check the Pressure
As babies grow, their feet get rounder. This can interfere with the pulse oximeter’s ability to get a good reading as it places the sensor at an angle (instead of straight up and down), causing yellow notifications. When this occurs, Baby’s foot can also press up against the sensor causing pressure.
The Smart Sock 2 has a weight limit of about 18-25 lbs. and since every baby’s foot is different, some little ones can outgrow the Smart Sock sooner than others depending on the roundness of the foot.
Make sure that your Smart Sock placement & fabric sock size are correct and that you are rotating the Smart Sock from one foot to the other on a nightly basis.
Watch for Moisture
We recommend placing the Smart Sock on a clean, dry foot without any ointments or cream. Our Sock doesn’t absorb moisture as well as other fabric socks due to the Smart Sock sensor components and if moisture builds up, it can irritate your little one’s skin, similar to a diaper rash.
If your child tends to get sweaty or clammy feet while sleeping, we recommend ensuring a comfortable sleeping temperature, (breathable pj’s, a fan in the room, etc.) and limiting the amount of time they are wearing the Smart Sock.
Be Aware of Movement
If your baby seems uncomfortable due to teething, colic, or just likes to move, the constant movement can cause enough friction from the Smart Sock to create hot spots on their foot. If Baby’s skin is irritated enough, these hot spots can quickly progress into blisters. It’s the same as someone breaking in a pair of new shoes, where the shoe doesn’t match the foot. This causes repeated rubbing and irritation.
If a mark appears, Baby’s skin will need time to heal. Rest their foot with the mark on it and don’t put the Sock back on until the mark has gone away. Help support the healing skin by applying a barrier cream containing petroleum jelly or an equivalent several times during the day. When the mark is gone, you can put the Smart Sock 2 back on the foot, making sure that the placement & sock size is correct.
If you have any questions about whether your little one is wearing the Smart Sock 2 correctly, please take some pictures from a few different angles (top, bottom, side, etc.) and submit them to our Customer Care Team so they can check the fit. Send it to our team via the chat feature in the Owlet App or by emailing firstname.lastname@example.org.
We want to help you get the most out of your Smart Sock. Using the right fabric sock size and ensuring the proper placement will help provide an all-around better experience for you and your little one.
