If you've been looking for the best sleep clothing for your baby, you've probably heard the term "TOG rating." A TOG rating tells you how warm a piece of clothing will keep your baby. Since babies can't tell you if they're too hot or cold like adults can, it's important to know the TOG rating of their clothes so you can dress them properly for the temperature of their room.
A TOG rating is a measure of how much heat a baby's sleep sack or another piece of clothing traps. TOG stands for "Thermal Overall Grade." A higher TOG rating means that your baby will stay warmer at the same room temperature. It assesses the insulation—or amount of heat—provided by fabric on a scale of <1 to 3.5.
How warmly you dress your baby depends on how warm or cool their room is. For example, a TOG 1.0 sleep sack is good for a room temperature of around 68°F.
It's important to remember, however, that these are guidelines, not laws. Every baby has a different temperature tolerance. Make a habit of checking the temperature of the back of their neck or trunk when they wake up. If these places are cold, that could be a sign you need a higher TOG rating. If your baby consistently wakes up sweaty, you should consider cooler clothing.
If you have a house that's cold in the winter because of drafts or cold floors, your baby will also need warmer clothing. Consciously keeping room temperature between 68°F and 72°F may help your baby sleep better through the night and wake up happy and refreshed.
Some baby sleep clothes come with the rating printed on the tags. If your baby's sleepwear doesn't show the rating on its tag, it will likely be on the online listing or the company's website.
TOG ratings are hard to guess because fabrics can be deceiving. It's always a good idea to see what the manufacturer has to say.
Not all clothing has a TOG rating. Articles of clothing that don't cover an infant's feet do not have a rating. Our Magic Sleepsuit does not have a TOG rating because of the openings on the legs.
The best practice for your baby's sleep temperature is to dress them only in the amount of sleepwear they need. If your baby is too warm, it can have a negative impact on their sleep quality. The most accurate way to see how warm your baby is is to feel the back of their neck or trunk.
If you're worried about your baby's temperature, here are a few ideas to help:
Safety is most important when it comes to your baby's sleep environment. The temperature of the room can affect your baby’s quality of sleep.
Be sure to check the TOG rating on your infant's sleepwear before putting them to bed. If you're unsure about what rating they need, keep a sleep journal and adjust as needed.
