Frequently Asked Questions
How can I tell if my baby is overheating while wearing a sleep sack?
Check the baby’s neck and chest — if they feel hot and sweaty or flushed, the child may be overheating. Also watch for rapid breathing or restlessness. A cool-to-warm hand on the chest is normal; persistently hot skin, damp hairline, or vomiting indicate overheating and you should remove layers and lower room temperature.
Which TOG should I pick to reduce overheating?
Choose lower TOG values for warmer rooms: 0.5 TOG for rooms above ~72°F, 1.0 TOG for roughly 68–75°F depending on how warmly you dress the baby underneath, and avoid thick 2.5+ TOG for hot-night climates. Always pair TOG choice with room temperature and what the baby wears under the sack (onesie vs long-sleeve).
Is bamboo-rayon or cotton better for a child who overheats?
Both are breathable, but they behave slightly differently: lightweight knitted cotton breathes and is durable through washes, while bamboo-derived rayon often feels cooler to the touch and wicks moisture well. If your priority is a cool feel, bamboo-rayon is a strong choice; if you want long-term ruggedness and straightforward care, go with knitted cotton.
