What does TOG mean for baby sleep sacks?
TOG stands for **Thermal Overall Grade**, a unit measuring how warm a fabric keeps your baby. Higher TOG = more insulation.
How do I know if my baby is too hot or too cold at night?
Check your baby’s **neck and chest**. If sweaty, reduce a layer. If cool, add a thin layer. Hands and feet are less reliable indicators.
Can I use a blanket instead of a TOG sleep sack?
No. Blankets increase the risk of **unsafe sleep**. TOG-rated sacks provide warmth without loose bedding.
Should I choose a higher TOG for newborns?
Not automatically. The guide doesn't raise the TOG for newborns: overheating is the bigger risk, so dress for the room temperature and check your baby's chest or the back of the neck.
Do I need different TOG sacks for different seasons?
Yes. Many families use **2–3 TOG options** (e.g., 0.5, 1.5, 2.5) to adjust for seasonal room temperatures.
Is it safe to swaddle with a TOG sleep sack?
Only if using a **swaddle-specific sack** designed for newborns. Once your baby shows signs of rolling, stop swaddling and switch to arms-free.
What room temperature is best for baby sleep?
The Lullaby Trust recommends 16–20°C (about 61–68°F) for baby sleep, with a lightweight, well-fitting sleep bag. Check your baby's chest or the back of the neck to see if they are too hot.
