FAQs

Why are my baby’s hands and feet cold at night? Hands and feet can run cooler naturally. Use chest/back of neck as your comfort check instead.

What temperature should the room be? Many families aim for a comfortable range around 16–20°C, but the key is dressing appropriately and checking your baby’s comfort.

How often should I check my baby’s temperature? If you’re changing sleepwear or TOG, do a quick comfort check after they’ve been asleep for a short time. After that, most parents only check if baby seems unsettled.
