Overheating increases sleep-related SUID risk. Signs that an infant is too hot include sweating, damp hair, flushed cheeks, heat rash, and breathing rapidly.

The room temperature should be comfortable for a lightly clothed adult.

Many infant care providers and parents are concerned that an infant will get cold without a blanket. Blankets can increase the risk of SIDS and accidental suffocation.  Instead of a blanket, use the general guideline of dressing an infant in clothes, sleepers or a nonrestrictive sleep sack that provide for one layer more than would typically be comfortable for an adult.

Swaddling is NOT allowed in early learning environments. Swaddled infants may roll more easily from back to stomach, with no ability to use their arms for support. Overheating may also occur if an infant is swaddled.
