What should be done if a newborn's thermoregulation is unstable?

Ensuring a newborn maintains stable thermoregulation is critical for their health, as they are particularly vulnerable to hypothermia. The recommended approach is to postpone bathing until the newborn's temperature stabilizes. Bathing a newborn while they are still struggling to maintain their body temperature can increase the risk of hypothermia, as the water can rapidly draw heat away from their small bodies.

Keeping the newborn warm and ensuring that their temperature is stable takes precedence over bathing. This means focusing on adequate thermal protection through methods such as swaddling them in warm blankets, skin-to-skin contact with a caregiver, or using heated environments. Such practices help to promote warmth in a stable manner before considering a bath or any other procedures.

The other options would not provide the necessary support for a newborn with unstable thermoregulation. Immediate bathing could lead to further temperature instability, while merely wrapping the baby in a blanket without checking their temperature does not ensure their needs are being adequately met. Drastically increasing room temperature might not be practical and could pose other risks.
