Yes, you can give bottled water to babies after they are older than six months. The US Food and Drug Administration (FDA) states that you can give low-fluoride bottled water to your baby when it is necessary
Types Of Bottled Water
There are three types of bottled water: mineral water, packaged drinking water, and distilled water.
Mineral water contains high quantities of total dissolved minerals. These minerals could be present naturally in the water extracted from the ground (groundwater) or taken from a natural underground spring (spring water). Alternatively, a manufacturer may add minerals that make the water tasty and good for health as well.
Packaged drinking water goes by several names such as packaged water, purified water or packaged purified water. Sourced from lakes, rivers, or even public taps, the water goes through UV treatment and reverse osmosis for improved taste. Packaged drinking water contains a few natural minerals that give the water its distinct flavor.
Distilled water is water in its purest form, without the presence of any dissolved gases or minerals. It is seldom sold for dietary consumption and is used for industrial purposes. It tastes bland.
Therefore, when you buy bottled water in the supermarket, it is most likely to be mineral water or packaged drinking water.
What Are The Bottled Water Requirements For Babies?
According to the US FDA and the NHS, bottled water for babies should meet the following requirements:
Less sodium: The sodium (Na) content should be less than 250mg per liter of water.
Low sulfate: Less than 250mg of sulfate (SO4) in a liter of water.
Select “low-fluoride” versions: Most packaged drinking water, even those with added minerals, have an average of 0.11mg of fluoride per liter or ppm (parts per million), which is safe for babies. If a version with a lesser level of fluoride is available, then that can be your choice.
