Under a Love to Dream swaddle, your baby needs anywhere from just a diaper to a full set of pajamas, depending on the room temperature and the swaddle’s TOG rating. The general rule from the American Academy of Pediatrics is simple: dress your baby in one layer more than you’d wear in the same room. The swaddle itself counts as a layer, so the clothing underneath should be minimal enough to prevent overheating.
Match Layers to TOG Rating and Room Temperature
Love to Dream swaddles come in several TOG ratings, each designed for a different temperature range. TOG measures how much warmth a fabric traps, so a higher number means a warmer swaddle and fewer layers needed underneath.
- 0.2 TOG (75°F to 81°F): A diaper only, or a short-sleeve bodysuit at most. This is the lightest option, meant for warm rooms and summer months.
- 1.0 TOG (68°F to 75°F): A short-sleeve or sleeveless bodysuit. This covers the comfortable middle ground most nurseries fall into.
- 1.5 TOG (64°F to 72°F): A long-sleeve bodysuit or light pajamas. The overlap with the 1.0 TOG range means you can adjust based on whether your baby runs warm or cool.
- 2.5 TOG (61°F to 68°F): Long-sleeve pajamas, potentially with a sleeveless bodysuit underneath. This is the go-to for cooler rooms in fall and winter.
- 3.5 TOG (below 61°F): Long-sleeve pajamas plus a bodysuit layer. This is the warmest combination and only necessary for genuinely cold rooms.
Love to Dream notes that these are guides, not rules. Every baby is different, and factors like your baby’s health, body composition, and the specific conditions in your nursery all play a role.
Best Fabrics for Base Layers
Cotton is the classic choice for baby sleepwear, and it works perfectly well under a swaddle. But if your baby tends to sleep hot or sweaty, bamboo viscose is worth considering. Bamboo fibers are about 40 percent more absorbent than organic cotton and evaporate moisture faster, which helps keep skin dry overnight. The fiber structure also allows more air circulation than cotton, making it a strong option for warmer climates or babies who overheat easily.
Whatever fabric you choose, avoid anything with hoods, strings, or loose material. A fitted bodysuit or a simple set of pajamas is ideal. The Love to Dream swaddle already covers your baby’s torso and arms, so bulky clothing underneath adds unnecessary warmth and can bunch up uncomfortably.
What to Avoid Underneath
Skip hats entirely for indoor sleep. The AAP specifically recommends against putting a hat on your baby indoors after you’re home from the hospital. Babies release excess heat through their heads, and covering it increases the risk of overheating.
Avoid doubled-up swaddles, extra blankets tucked inside, or thick fleece layers. The whole point of a TOG-rated swaddle is that it provides a predictable, tested level of warmth. Adding unpredictable insulation defeats that purpose and makes it harder to gauge your baby’s temperature. If the room is cold enough that you feel your baby needs more than pajamas plus the swaddle, it’s better to raise the room temperature or move to a higher TOG swaddle than to pile on layers.
How to Tell if You Got It Right
The best way to check is to feel your baby’s chest or the back of their neck. These areas give a more accurate read on core temperature than hands or feet, which tend to feel cool even when a baby is perfectly comfortable. You’re looking for skin that feels warm but not hot or damp.
Signs your baby is overdressed include sweating, damp hair, flushed or red skin, and restlessness. Some babies overheat without sweating at all, so red cheeks and a hot chest are the more reliable indicators. If your baby’s chest feels clammy or noticeably warmer than your own skin, remove a layer or switch to a lower TOG swaddle.
On the flip side, a baby who feels cool to the touch on their chest (not just their hands) or seems unsettled despite being fed and dry may need an extra layer. Cold hands and feet alone are normal for newborns and don’t necessarily mean they need more clothing.
Practical Setups by Season
In summer, most homes sit between 72°F and 80°F. A 0.2 TOG swaddle with just a diaper works well at the warmer end of that range. If you keep your nursery air-conditioned around 72°F to 74°F, a 1.0 TOG with a short-sleeve bodysuit is a comfortable combination.
In winter, nursery temperatures typically drop to the mid-60s unless you heat the room overnight. A 2.5 TOG swaddle with long-sleeve pajamas handles this range well. For rooms that dip below 61°F, the 3.5 TOG paired with pajamas and a bodysuit provides enough warmth without loose blankets, which are not safe for infant sleep.
Spring and fall are the trickiest because nighttime temperatures can swing significantly. Having both a 1.0 TOG and a 2.5 TOG on hand lets you adjust without overthinking the clothing layers. On a mild night, the 1.0 TOG with a long-sleeve bodysuit covers you. On a cooler night, swap to the 2.5 TOG with the same bodysuit and you’re set.
