What's the difference between an arms up sleep sack and a traditional swaddle?

Arms up sleep sacks keep baby's arms free while providing gentle body support, allowing hands-to-mouth contact for self-soothing. Traditional swaddles wrap the arms tightly, which some babies find restrictive as they develop.

Will my baby get too hot in this sleep sack?

The 1.0 TOG rating is designed for rooms between 68–75°F. Monitor your baby for signs of overheating (sweating, flushed skin), and adjust room temperature or sleepwear layers accordingly.

How do I know if my baby is the right size for this model?

This sleep sack fits babies weighing 8–13 lbs, typically newborns 0–3 months old, though individual sizes vary. Ensure there's no excess fabric bunching around the neck or armholes for safe fit and maximum comfort.

Buying Tip

Check your nursery temperature before purchasing—this 1.0 TOG rating is designed for warmer rooms (68–75°F). If your baby sleeps in cooler environments, consider layering with appropriate sleepwear or selecting a higher TOG option. Always follow safe sleep guidelines: baby should sleep on their back, and the sleep sack should fit snugly without excess fabric.
