Baby's bath is often presented as a straightforward moment. In practice, the first few times raise many questions: what temperature to choose, how much water to put in, how often to wash a newborn, how to hold them, and what products to use?
The good news is that French and international recommendations agree on the essentials: water around 37°C, a bath prepared before undressing the baby, and continuous adult supervision within arm's reach. Depth, duration, and frequency figures are practical guidelines—not universal safety thresholds. Here's a verified, step-by-step summary.
|
6 KEY GUIDELINES
• Bath water: aim for 37°C; for the French public, do not exceed this guideline.
• Warm, draft-free room: 22 to 25°C is the usual French guideline.
• Depth: 8 to 12 cm according to Assurance Maladie; this low level does not prevent drowning.
• Indicative duration: a few minutes, often 5 to 10 minutes depending on age and comfort.
• Frequency: 2 to 3 baths per week are generally sufficient; there is no universally proven optimum.
• Safety: continuous and close supervision, without phone or absence, even very brief.

What temperature for baby's bath?
International recommendations converge around 37°C. France and Norway recommend a maximum of 37°C, Germany 36 to 37°C, while some Australian authorities indicate 37 to 38°C. For an article aimed at the French public, the most prudent guideline remains 37°C, not to be exceeded.
Touch does not provide a numerical measurement: first, mix all the water to eliminate hotter areas, then preferably check it with a bath thermometer. The elbow or inner wrist can also verify that the water feels pleasantly warm, as suggested by several foreign authorities, but this check remains subjective.

How often should a baby be bathed?
Two to three baths per week are generally sufficient for a newborn's hygiene. This summary is consistent with France, the UK, the US, Canada, and Australia; Germany and Sweden sometimes suggest an even less frequent rhythm. A daily bath may still be possible if the baby enjoys it and their skin tolerates it, but it is not necessary.
No study establishes an ideal number valid for everyone. An observational study associated more frequent bathing with more atopic dermatitis at 3 months, but it cannot be definitively stated that baths are the cause. The prudent approach is therefore to avoid superfluous baths and products, then adapt the routine to the child's skin.
On non-bath days, clean the face and hands when necessary, as well as the bottom and genitals with each diaper change. If your child has very dry skin, eczema, is premature, or has a skin condition, ask your midwife, doctor, or pediatrician for advice on adapting the frequency and products.
When to give the first bath and what to do about the umbilical cord?
The World Health Organization recommends waiting at least 24 hours after birth before the first bath, primarily to limit cooling. A systematic review of 16 studies involving 39,020 newborns supports this, while noting that the certainty of several results is low: the most well-supported benefits mainly concern thermoregulation and early breastfeeding.
After this delay, recommendations vary regarding the umbilical cord. France, Sweden, Finland, and Germany generally allow bathing before it falls off if the cord is not infected and is thoroughly dried afterward. In the United States, the American Academy of Pediatrics more cautiously advises sponge bathing until it falls off. Available trials have not shown an increased risk of infection with tub bathing under good hygiene conditions, but they remain limited in size. Therefore, primarily follow the instructions of the maternity ward and the professional who knows your child.
The bath can be given in the morning or evening. Most importantly, choose a time when the baby is awake, available, and you are not rushed. Late afternoon or early evening can have a calming effect on some infants, but it is not a universal rule.
Prepare everything before undressing baby
Good organization is not just practical; it prevents you from having to step away from the bath. Place within reach:
Check that the room is warm and free of drafts. The French guideline is 22 to 25°C; other recommendations indicate approximately 21 to 24°C or at least 23°C. Place your phone out of reach or on silent mode. Remove any jewelry that could scratch, wash your hands, and ensure the bathtub is clean and stable.
How to bathe baby in 7 steps
For a young infant, about 5 minutes is often enough; several foreign recommendations suggest a range of 5 to 10 minutes. This is not a demonstrated time limit. If the baby gets cold, cries a lot, or seems uncomfortable, simply shorten the bath.
The safety rule that allows no exceptions
|
NEVER LEAVE BABY ALONE IN THE BATH
• Stay within arm's reach and keep your eyes on them constantly.
• A seat, bouncer, or bath ring never replaces the active presence of an adult.
• If you need to leave the room, even for a few seconds, take the baby out, wrap them in a towel, and take them with you.
• Do not use your phone during bath time.
• Always keep one hand on the baby if you reach for an object.

Do not run water or empty the tub while the baby is in it: the temperature can change abruptly and the faucet can remain scalding hot. Once the bath is finished, empty and clean the tub, then dry the toys.
What products to use for skin and hair?
For routine cleaning, water alone is often sufficient during the first few weeks. If a cleanser is necessary, choose a mild one, in small quantities, without fragrance, antibacterial agents, or essential oils, with a neutral or slightly acidic pH. The mention "for baby" alone is not enough to prove that a formula is suitable for all skin types.
It is not necessary to wash hair at every bath: depending on needs, one to three times a week is generally sufficient, unless medically indicated. Rinse without splashing the face. After the bath, pat dry rather than rubbing.
What studies actually show about skin
A randomized trial involving 307 full-term newborns concluded that a specific mild liquid cleanser was not inferior to water alone for skin water loss. This result cannot be generalized to all products. Conversely, the Scandinavian PreventADALL trial did not show eczema prevention with frequent baths containing oil; a slight transient increase in water loss was observed.
A Cochrane review of 33 studies and 25,827 infants concludes that preventive skin care, including emollients, probably does not prevent eczema in healthy babies and could increase certain skin infections. This does not call into question their use for treating diagnosed eczema: in this case, the routine should be individualized with a healthcare professional.
What to do if baby cries during bath time?
Some newborns dislike being undressed, get cold quickly, or are surprised by the sensation of water. First, check the room and bath water temperature, use slow movements, talk to them, and hold them confidently. Choose a time when they are neither very hungry nor exhausted.
If they remain uncomfortable, take them out, wrap them, and try again another day. A daily bath is not essential. To better understand other possible causes of discomfort, also consult our guide Why Baby Cries: Understanding Infant Cries.
The bath thermometer: useful, but not a guarantee of safety
A thermometer provides a readable reference after mixing the water. French authorities recommend it; several foreign authorities also accept the elbow or inner wrist as a tactile check. It is therefore not indispensable in all recommendations, but remains the most objective tool for verifying 37°C. It does not replace mixing the water or supervision.

Baby bath checklist
FAQ: All frequently asked questions about baby baths
1. What is the ideal temperature for a baby bath?
Aim for 37 °C, and to follow the French guideline, do not exceed this temperature. International recommendations are generally between 36 and 38 °C. Mix all the water before measuring to avoid a hotter spot in the tub.
2. Is a bath thermometer essential?
It is recommended in France and provides the most objective reference, but several foreign authorities accept the elbow or the inside of the wrist. Without a thermometer, the water should feel pleasantly warm, never hot.
3. Can you test the water only with your finger?
The finger does not provide a numerical measurement. Instead, use a thermometer; otherwise, the elbow or the inside of the wrist offer a more commonly recommended tactile check. In all cases, mix the water before testing.
4. How much water should I put in the bathtub?
Assurance Maladie recommends about 8 to 12 cm of water. Other countries suggest 8 to 13 cm. These are not safety thresholds: even with very little water, continuous supervision is essential.
5. How long should the bath last?
For a young baby, about 5 minutes is often enough; several authorities suggest 5 to 10 minutes. Adjust to their comfort and prepare the towel before starting.
6. How many baths should be given per week?
Two to three baths per week are generally sufficient, without being a universal scientific optimum. Between baths, clean the face and hands as needed, and the diaper area with each change.
7. Can you bathe a baby every day?
Yes, if they enjoy this ritual and their skin tolerates it, but it's not necessary for hygiene. Use little product and space out baths if their skin becomes dry or irritated.
8. From what age can you give a bath?
The WHO recommends waiting at least 24 hours after birth. Upon returning from the maternity ward, this period has normally passed, unless there are specific instructions from a health professional.
9. Can a newborn be bathed before the umbilical cord falls off?
France and several Nordic countries allow it if the cord appears healthy and is then well-dried; American recommendations prefer sponge bathing until it falls off. Follow the care advised by the maternity ward.
10. Is it better to give a bath in the morning or in the evening?
Both are suitable. Choose a calm moment when the baby is awake and you have time. Some babies relax more with a bath at the end of the day.
11. Can you give a bath immediately after a bottle or feeding?
There is no mandatory schedule. If your baby regurgitates easily or seems uncomfortable after eating, simply wait until they are calm and available rather than following a rigid rule.
12. Can you add hot or cold water during the bath?
No. Prepare and adjust all the water before placing the baby in. Never run water when they are in the tub: the temperature can change abruptly, and the tap can be hot.
13. Does a bath seat or recliner allow you to move away?
Never. These accessories can facilitate positioning, but they do not replace active, continuous supervision within arm's reach.
14. Which soap should I choose for the bath?
Water alone is often sufficient at first. If a cleanser is needed, choose a mild one, without fragrance, antibacterial agents, or essential oils, with a neutral or slightly acidic pH, and use sparingly.
15. Should hair be washed at every bath?
No. Depending on needs, a mild shampoo one to three times a week is generally sufficient, unless medically indicated.
16. What to do if the baby cries as soon as they are put in the water?
Check the water and room temperature, slow down your movements, and talk to them. If they don't calm down, stop the bath and try again another day: their hygiene will not suffer.
17. What to do if you have to leave the bathroom?
Immediately take the baby out of the water, wrap them in a towel, and take them with you. Never leave them alone, even to open a door or answer the phone.
In summary
A calm bath relies less on a multitude of accessories than on a few constant guidelines: water around 37 °C, a sufficiently warm room, a shallow depth of water, a brief bath, and uninterrupted adult presence. The thermometer helps check the temperature; only your attention ensures safety.
