Quick answer
If your baby wakes up cold, the most likely cause is a blanket that is too thin, too small, or made from fabric that doesn't retain warmth well. Matching the blanket's TOG rating to your room temperature and choosing a generously sized, breathable material can solve the problem.
Why a cold baby is usually not a health risk
Babies have immature circulation, so their hands and feet often feel cool even when their core is warm. Before you change blankets, check your baby's chest or back—if that skin feels warm, your baby is likely fine. A cool chest or back, however, means the blanket isn't providing enough insulation.
The trade-off between warmth and breathability
A very thick blanket can trap too much heat, increasing the risk of overheating—a known SIDS risk factor. The goal is a blanket that is warm enough without being heavy or suffocating. Breathable natural fibers like organic cotton or bamboo rayon strike this balance better than synthetic fleece or heavy acrylic.
Diagnose your baby's cold-night issue in 3 steps
- Symptom: Your baby wakes up crying or fussy, and their hands or feet feel cool to the touch.
- Likely cause: The blanket is either too thin for the room temperature (wrong TOG), too small to stay tucked, or made from a fabric that doesn't retain warmth (e.g., thin muslin). Check the room temperature first. If it's below 20°C (68°F), a TOG 2.5 or higher is usually needed.
- Corrective action: Switch to a blanket with a TOG rating matching your room temperature. For rooms 20-23°C (68-74°F), try a TOG 2.5 blanket like the Toddler Blanket. For warmer rooms, a TOG 1.0 or a lightweight organic cotton blanket like the 3D Jacquard Knit Baby Blanket works well. Ensure the blanket is large enough to be tucked around the mattress if your baby is still in a crib. If your baby still feels cold after one night with the new blanket, the room may need a small heater or you may need a sleep sack instead of a loose blanket.
- When to choose another option: If your baby is under 12 months old or rolls over frequently, a wearable blanket (sleep sack) is safer than a loose blanket. Loose blankets are not recommended for infants due to suffocation risk. For older toddlers who kick off covers, the Toddler Blanket's larger size (57x39") helps it stay in place.
