What temperature should the baby bath be at? The complete guide

Too hot, the water can burn the baby’s fragile skin; too cold, the bath becomes unpleasant and makes the baby cry. So, what temperature should the baby’s bath be? The answer lies in one number — about 37 °C — but a few simple rules make all the difference for a safe and serene bath.

What is the ideal temperature for baby baths?

The ideal water temperature is around 37 °C, or the body temperature. A range of 36 to 38 °C It fits perfectly: the baby is relaxed, neither surprised by the cold nor at risk of burning. For newborns, whose skin is particularly delicate and still has difficulty regulating their temperature, it is better to aim for exactly 37 °C.

The temperature of the room also matters

Before even thinking about water, check the temperature of the bathroom: aim for it 22 to 24 °C, Without air circulation. A baby cools down very quickly once out of the water; a well-heated room prevents the cold from setting in when wiping them down.

How to measure the water temperature?

Three methods, from the most reliable to the most approximate:

• The bath thermometer — the safest. Instantaneous and precise reading. Some bathtubs, like the Foldable baby bathtub with built-in thermometer, They display the water temperature in real time directly: you can no longer be mistaken.
• The elbow or wrist test — dip your elbow in the water: it should be just warm, neither hot nor cold. Handy for emergencies, but less precise.
• To be avoided Judging by the hand or the eye. Your hands tolerate temperatures much higher than the baby’s skin.

Too hot or too cold water: the risks

A newborn's skin is much thinner than an adult's: beyond 38-39 °C, With the risk of burns becoming real even within a few seconds. Conversely, water below 35 °C cools the baby quickly and may cause them to cry or tremble. This is why it is important to always check the temperature just before you immerse the baby.

How long should the bath last?

For a newborn, 5 minutes suffice; up to 10 minutes For a bigger baby who likes to splash around. The water cools quickly, so there’s no need to keep it on for long. And there’s no need to bathe the baby every day: 2 to 3 times a week is enough in the first few months.
