When it comes to moisturising your baby, every detail counts for protect your health. Should we opt for bottled water? Can we really trust tap water? These questions come up every time we prepare a bottle.
However, many preconceived ideas continue to circulate, whether about spring water or mineral water. Although perceived as the safest, mineral water is far from being the best water for babies.
In this article, we take a look at the situation to help you sort out what's real from what's not. The aim is to help you make a calm and informed choice, for the well-being of your baby.
Contrary to popular belief, the health authorities are quite clear: in France, tap water is ideal for babies. It undergoes rigorous checks every day on dozens of quality criteria, guaranteeing safe drinking water.
In fact, it is the most closely monitored food in the country. The Ministry of Health recommends its use for preparing baby bottles, as long as its potability is confirmed. This is the case in the vast majority of France.
For complete peace of mind, you can consult the results of analyses of your local authority's network at the town hall or directly on the government's website: eaupotable.sante.gouv.fr
As well as being healthy for your baby's wellbeing, water from your home is also more environmentally friendly (zero plastic waste, no transport emissions), more economical (up to 300 times cheaper than bottled water) and much more practical for everyday use (no more packs to carry, store and sort/dispose of).
Used properly (see our tips at the end of this article), this water is an excellent option for hydrating your baby, while making life easier for the whole family.

Many parents think they are doing the right thing by choosingmineral water to prepare their baby's bottles. It is often perceived as healthier, especially since some brands, such as Evian or Mont RoucousIn some cases, the water is labelled "suitable for infants". But be careful: this does not mean that the water is ideal for your child's health. Why is this? Because natural mineral waters are not subject to the same potability criteria as those set by the WHO.
As the paediatrician Emmanuel Delmas Mineral water is not at all necessary for children's development and nutritional needs.
Let's take a look at the 3 myths about this water to give your little one the best hydration.

This is a widely-held idea, but it has no scientific basis. Many people believe that water with a very low mineral content is softer, more digestible and therefore necessarily better for infants.
In reality, no. Water with a low mineral content cannot be considered potable according to WHO criteria. It no longer meets physiological needs. For a growing baby, this is obviously far from ideal.
Just look at the composition of breast milk: the most suitable food for toddlers is naturally rich in minerals such as calcium and magnesium.
It therefore makes no sense to completely remove these elements from water. Your baby is not a car battery or an iron for whom we reserve the use of mineral-free distilled water.
When a baby seems uncomfortable, constipated or prone to colic, many decide they need a change of water. As a result, parents opt for mineralised water in the bottle, designed to "promote transit.
However, no scientific study confirms that this type of water relieves and improves digestion in babies. Paediatrician Emmanuel Delmas is very clear: "Parents often think that their baby is constipated, but this is not the case. The first thing to do when in doubt is to consult a health professional. But the second question is, is there any point in taking these specific mineral waters in case of constipation? The answer is no.
Changing water is not the solution. It's better to seek professional advice rather than rely on preconceived ideas.
At first sight, it's reassuring: the water is bottled, sold by major brands, sometimes even labelled "special for infants". So we tell ourselves that bottled water is cleaner, better filtered and therefore healthier.
But the reality of its quality is quite different. Numerous analyses have shown that the presence of microplasticsPFAS and chemical substances in several packs. Elements invisible to the naked eye, but well established and harmful.
And that's not all. Visit scandal Nestléinvolving the group Alma (owner of Cristaline), revealed that certain waters presented as "spring" or "mineral" were in fact taken from the public network, filtered using unauthorised processes and then sold at high prices.
Finally, it's hard to ignore the environmental impact: single-use plastic, transport emissions, polluting waste, etc.
Bottled water is far from being a sustainable, high-quality solution.
It's not what you first think. Yet bacterial contamination is one of the most common greater risks for your baby. Much more than the mineral content or the presence of chlorine or nitrates, it is the invisible bacteria and viruses that can cause the most serious damage to a newborn baby, whose immune defences are still fragile.
This risk is much more common than you might think, particularly with conventional filter jugs, which are often perceived as being safer. Poorly maintained, they become veritable breeding grounds for bacteria. L'UFC-Que Choisir doesn't mince his words and headlines his article: " Useless or worse ! ". For its part, ANSES is warning of the microbiological contamination linked to their improper use. A paradoxical situation when consumers are paying the price.
LAVIE has designed the UV-A filter carafe to prevent this from happening: an unfiltered solutionThis chemical-free, waste-free product eliminates bacteria, viruses, chlorine, pesticides and drug residues, while preserving the minerals essential for your newborn's growth.
Healthy, reliable water that's really suitable for toddlers.
With LAVIE's UV-A filter carafe, purifying your water is quick and easy - perfect for your child's health.
Here's how to do it:
Once the cycle is complete, the water is purified while retaining the essential minerals. You can then prepare your baby's bottle as usual, adding the infant milk.
Result: hydration and healthy waterIt contains no pollutants or chemicals, and is suitable for the whole family, especially toddlers.
If you're not using a purification system like the LAVIE UV-A carafe, it's essential to take the right steps to limit the risks associated with water quality.
These simple steps can help reduce the risk of bacterial contamination, but they do require rigour and vigilance on a daily basis.
Every day, tap water is still the best choice for preparing your baby's bottles. It's safer, more practical, more than reasonably priced and environmentally friendly. Of course, as long as it's drinkable and used in the right conditions.
But like mineral or spring water, it can contain invisible contaminants: chemical residues, microplastics or harmful bacteria. And these risks are even more worrying for infants, whose immune systems are fragile.
To guarantee truly healthy water, it is therefore advisable to purify it using effective, long-lasting technology.
The solutions developed by LAVIE, such as the UV-A filter carafe or the Opropre under-sink filter, make it possible toeliminate pollutants while preserving the minerals essential for your baby's growth.
The result is safe water, perfectly suited to the needs of your baby and the whole family.
Tap water is recommended by the health authorities for your baby. And why is that? Because in France, it undergoes strict checks every day to guarantee its quality. Combined with a purification system like the LAVIE UV-A carafe, it becomes even more reliable: it eliminates pollutants while preserving the minerals essential to your child's growth.
Yes, tap water is ideal for infants and is even recommended by the health authorities for preparing baby bottles with infant milk. For greater peace of mind, you can consult the results of your local water analyses, available from your local council or directly from the government website: eaupotable.sante.gouv.fr
Certain spring or mineral waters, such asEvian or Mont RoucousThese are labelled "suitable for infants". But for a longer-lasting, much cheaper and just as reliable option, purified tap water is ideal. Combined with a LAVIE, it guarantees healthy hydrationIt is perfectly adapted to the needs of your baby and the whole family.
