# Dressing your baby for sleep: layers, overheating and TOG ratings > The AAP rule: dress your baby in no more than one layer beyond what you would wear to feel comfortable in the same room. No indoor hats and no loose blankets. Source: https://actuallysleeping.net/guides/what-should-baby-wear-to-sleep/ Publisher: Actually Sleeping LLC · Reviewed by Dr. Samantha Abrahamson, PharmD (PA pharmacist license RP1012588, NPI 1730650979) Following the AAP’s rule, put your baby in no more than one layer beyond what you would wear to feel comfortable in the same room. Skip hats indoors and skip loose blankets. Keep an eye out for overheating: sweating, flushed skin, or a hot chest. TOG is a warmth rating for sleep sacks; pick one that, together with the clothes underneath, comes to about one layer more than you are wearing. **Up at 3 a.m. reading this?** Tomorrow night does not have to look the same. Actually Sleeping writes a plan around your baby, coaches you thoroughly before night one so you start with confidence, and checks in with you 1:1 each day until your baby sleeps through, backed by a full-refund guarantee.

Layering your baby’s clothing is safer than relying on blankets, and the AAP recommends keeping the room at a comfortable temperature. No specific room temperature is given by either the AAP’s parent site or the NIH Safe to Sleep campaign. The guidance centers on how your baby feels rather than a thermostat reading. ## How to tell your baby is too warm These are the signs listed by the NIH Safe to Sleep campaign: - Sweating - Skin that is flushed, red or hot - A chest that is hot when you touch it Feel the chest or the back of the neck rather than the hands and feet. If your baby is sweaty, take off a layer. ## Hats and covering the head The AAP advises against putting a hat on your baby indoors after you are home from the hospital; hats belong to the first hours after birth or the NICU. Safe to Sleep adds that your baby’s head and face should remain uncovered while sleeping. If you are double-checking layers because your baby keeps waking, getting the temperature right matters, but it is seldom the full explanation. The waking itself is what Actually Sleeping fixes. ## What a TOG rating means TOG is short for thermal overall grade, a warmth rating that manufacturers print on sleep sacks and swaddles; the higher the number, the warmer and thicker the sack. TOG does not appear in the AAP’s guidance, and brands vary in how they rate products and which room temperatures they suggest. Treat the manufacturer’s chart as a starting point and adjust for your baby. ## How it all fits together | Room feels | You would wear | A typical baby setup | |---|---|---| | Warm | A T-shirt | A short-sleeve bodysuit, or a bodysuit under a light sleep sack | | Comfortable | Light long sleeves | A long-sleeve sleepsuit with a light-to-medium sleep sack | | Cool | A sweater | A long-sleeve sleepsuit with a warmer sleep sack | These illustrate the one-extra-layer rule rather than setting firm requirements. Your baby’s skin is what really tells you. Hands and feet frequently feel cool even when a baby is warm enough, since they are small and exposed; judge by the chest and neck. ## What to avoid - **Loose blankets and quilts.** Leave them out of the sleep space throughout the first year. - **Weighted sleep sacks or swaddles.** According to the AAP, weighted products on or near a baby are not safe. Read [weighted sleep sacks](https://actuallysleeping.net/guides/are-weighted-sleep-sacks-safe/). - **Swaddling once your baby is trying to roll.** At the first signs of rolling, stop swaddling and switch to an arms-out sleep sack. - **Hoods, hats and heavy fleece in a warm room.** - **Heaters or electric blankets close to the crib.** ## When the real question is night waking Lots of parents begin comparing TOG ratings because their baby keeps waking and they suspect the baby is too cold or too hot. A baby who is overly warm or chilly may wake more, so it is worth getting right. Still, temperature is seldom the full explanation. A baby who wakes several times a night in a comfortable room while dressed correctly is usually waking between sleep cycles and needing help to drift off again.

Neither the AAP nor the NIH sets a specific number. They recommend a comfortable room temperature and dressing your baby in one layer more than you would wear, then checking for sweating, flushed skin, or a hot chest. ### Which TOG sleep sack is right for my baby? TOG is a warmth rating set by manufacturers, not an AAP standard, and it varies between brands. Start with the maker’s chart, then pick clothing and a sack that together come to about one layer more than you have on. ### Does my baby need a hat for sleep? No. The AAP advises against a hat indoors once you are home from the hospital. A hat can overheat a baby, and the head and face should remain uncovered during sleep. ### My baby has cold hands. Should I add a layer? Not necessarily. Hands and feet commonly feel cool. Check the chest or the back of the neck instead. If they feel comfortable and are not sweaty, your baby is warm enough. ## References 1. [HealthyChildren.org (AAP).
