FAQ
Reader questions
Are sleeveless sacks better for hot weather than short-sleeve options?
Sleeveless sacks maximize breathability and reduce overheating, while short-sleeve options offer slightly more arm coverage for cooler rooms.
Can a sleep sack replace a blanket in a crib for summer sleep?
Yes, a properly fitted sleep sack eliminates loose bedding, creating a safer sleep environment and helping maintain a consistent temperature.
How do I know if the TOG rating is suitable for my nursery climate?
Measure your average room temperature at night; choose a lower TOG below 0.5 for warm climates and a higher TOG only if air conditioning drops temperatures significantly.
What should I do if my baby seems restless in a new sleep sack?
Check for proper sizing, ensure the neckline is not too loose, and look for soft, tag-free materials, then gradually introduce the sack during daytime naps.
