What should baby wear underneath?
Use the sleep sack over your baby’s usual sleepwear, like a bodysuit, romper, or pajamas. What goes underneath depends on the room temperature and the TOG rating of the sack. A wearable blanket counts as one layer, so you do not need loose blankets on top.

Can baby wear it on its own?
Sometimes, yes — in warmer rooms, some babies may only need a light layer underneath. In cooler rooms, parents often use long-sleeve or footed pajamas underneath instead. The best guide is room temperature, TOG, and how baby’s chest or back feels, not just hands or feet.

Do cold hands mean baby is too cold?

Not always. Cold hands and feet are very commonly mentioned by parents, but they are not the best way to judge overall temperature. A better check is baby’s chest or the back of the neck. Cool hands can be normal even when baby’s core temperature is fine.

How do I know if baby is too hot?
Overheating matters more than slightly cool hands. Check the chest or back of the neck for warmth and sweatiness, and avoid over-layering. Guidance from pediatric safe-sleep sources commonly says babies should wear about one more layer than a comfortable adult, and wearable blankets are preferred over loose bedding.

Do I still need a blanket over this?
No loose blanket is needed over a sleep sack. A safe infant sleep bag or wearable blanket is meant to replace loose blankets and help keep the sleep space clear.

Can I use this once baby starts rolling?
If it’s an arms-free sleep sack, yes — that is generally the direction parents move toward. But swaddling should stop as soon as baby shows signs of trying to roll. That is a major official safe-sleep recommendation.

Are weighted sleep sacks safe?
No — major safe-sleep sources including the AAP and NIH advise against weighted sleep sacks, weighted swaddles, and weighted blankets for babies.
