Frequently Asked Questions
What TOG should I choose for a summer newborn?
For warm rooms and hot nights choose a 0.5 TOG (lightweight) sleep sack or muslin swaddle. If your home is air-conditioned or nights are mild, a 1.0 TOG can be appropriate. Always base the choice on room temperature and how baby seems to sleep—check for sweating or cold hands/feet as cues.
Are sleep sacks safer than loose blankets?
Yes. Wearable blankets and sleep sacks remove loose bedding from the crib, reducing the risk of covering a baby's face. Choose items designed for safe sleep with secure closures, a proper neck fit, and breathable fabric to prevent overheating.
How should a summer baby be dressed under a 0.5 TOG sleep sack?
Dress your baby minimally under a 0.5 TOG sack. In very warm rooms a diaper-only or a lightweight onesie is often enough. Always check baby’s temperature by feeling their chest or back and avoid over-layering; the goal is comfortable, not warm-to-the-touch.
