Microwave feeding bottles: a risk of plastic micro- and nanoparticles
Provided, of course, that the bottle is made of plastic. Under the effect of heat, this material tends to release microscopic particles invisible to the naked eye. These particles will take advantage of the heat to mix with your baby's your baby's milk.
Since they generate no odor, cannot be seen, and their size does not allow them to alter the flavor of the preparation, they are undetectable. 🐱👤Pourtant, they are indeed millions to pass through your child's body at mealtime! Plastic baby bottles release micro-particles even when heated in a bain-marie or bottle warmer.
It should be remembered that these fine particles are considered to be disruptors disrupt the endocrine system from childhood to adulthood.
Among these plasticizersBisphenol A (BPA) and Phthalate have been progressively banned from manufacturing processes, according to very strict standards, including a law passed in France banning its use in 2015 and classification as a substance of very high concern (SVHC) in 2017.
But this component was replaced by Bisphenol S (BPS), which, a priori, has very similar characteristics.
Nutrient destruction: the side effect of microwave cooking...
Putting your baby's bottle in the microwave presents another problem: it destroys the essential nutrients, vitamins and minerals contained in the milk. For this reason, some parents choose to heat only the water first, and add the industrial milk powder afterwards. 🍼
This is obviously not an option for parents who have decided to opt for the breast pumpsince breast milk, once defrosted, requires no special preparation and must be warmed up before being offered to baby!
Which feeding bottle is safe to use in the microwave?

Not all materials disintegrate, nor are they the source of micro- and nanoparticle diffusion. Fortunately, they do! It's now possible to buy microwaveable baby bottlesglass or silicone baby bottles.
Note that the latter material has the advantage of not breaking in the event of a fall. And since babies don't yet have precise dexterity, entrusting them with an unbreakable feeding bottle is often synonymous with saving time and money!
2 alternatives for reheating a feeding bottle without using your microwave
There are other disadvantages to heating a baby's bottle in the microwave, such as uneven heating!
Some areas may be hotter than others. While stirring the milk well is sufficient, it will not be enough to cool the container itself, which may be almost boiling if heated in the microwave, while the milk inside will be barely lukewarm...
There's a very simple explanation for this oddity: the action of a microwave is not continuous. Unlike a conventional heat source, which heats up constantly, a microwave oven uses electromagnetic waves to stimulate the molecules present in the food. This creates molecular agitation, generating heat.
However, as these waves are emitted intermittently, the energy is not distributed evenly throughout the food! Some areas may absorb more energy than others.
We therefore recommend that you warm the bottle using one of these 2 alternative methods:
Electric bottle warmer
Invest in an electric bottle warmer or water heater specially designed for warming bottles. These devices are designed to heat milk evenly. Follow the manufacturer's instructions to ensure safe and efficient use.
Always be sure to test the temperature before giving your baby a bottle, to avoid any risk of scalding.
Did you know? L'Élhée adapter adapter has been designed to enable mothers to express, store and warm their milk directly in the Élhée bottle. This adapter is screwed onto BibRonds and Bubble Élhée training cups to make them compatible with Philips Avent and Medela breast pumps, as well as with severalwith several brands of bottle warmers portable bottle warmers (Munchkin, Mini Cupid, Tommee Tippee, Izybaby)! |
Water bath
Use the traditional bain-marie method. Fill a saucepan with water to heat, but do not boil. Then place the bottle in the water, making sure it's well submerged and won't spill.
Hot water will slowly transfer heat to the bottle more evenly than the microwave. Be sure to stir the milk regularly to ensure an even temperature.
In a nutshell
- Reheating a feeding bottle in the microwave can present certain risks, which is why many experts recommend alternatives safer alternatives.
- As mentioned above, the action of microwaves is not always uniform. hot and cold zones in the milk in the bottle. This poses a risk of burns to your baby.
- Some feeding bottles can release harmful substances when heated in the microwave. If the bottle is made from plastic materials, the risk is particularly high, and the endocrine system can suffer over the years.
- Glass and silicone baby bottles are considered free from this problem. The silicone will not break if baby drops it.
- Finally, reheating a feeding bottle in the microwave causes degradation of the nutrients present in breast milk. A paradox and a certain injustice when you consider that breast milk basically contains everything a young child needs to develop properly!
- It's perfectly possible to reheat a baby's bottle in a way other than in the microwave, for example in a bain-marie or with a bottle warmer.
