What Should Baby Wear to Bed at 34°C?
34°C is very warm for baby sleep, but many babies sleep safely at this temperature when dressed in minimal clothing and checked regularly for signs of overheating. If possible, keeping the room as cool as you comfortably can, or choosing a cooler room in your home, can also help your baby sleep better.

Always check your baby’s chest or back to judge warmth — hands and feet often feel cooler and are not a good indicator.
What Baby Should Wear to Bed at 34°C
Diaper only:
At 34°C, a diaper is usually enough. It keeps your baby cool while maintaining a comfortable base layer.
Optional: very light short-sleeve bodysuit:
Only if your baby seems unsettled with just a diaper.
Choose a thin, breathable cotton bodysuit that adds almost no extra warmth.
Why This Bedtime Outfit Works at 34°C
At 34°C, the room is hot enough that even thin fabrics can trap excess heat. A diaper alone keeps your baby cool, while an optional short-sleeve bodysuit can be added if they prefer a bit of coverage. Avoiding sleep sacks helps reduce the risk of overheating in very warm indoor environments.
If you can, try to keep your baby’s sleeping space as cool as possible — for example by using shade, a fan, or AC that is not blowing directly on them, or moving your baby to the coolest room in your home. Even small changes can make a hot night more comfortable.
