Soda water, also known as sparkling water, carbonated water, or seltzer water, has become an increasingly popular beverage in recent years. With its refreshing fizz and variety of flavors, many adults enjoy drinking soda water on its own or mixing it into cocktails. However, is this bubbly drink safe for babies to consume?
What is soda water?
Soda water is water that has been infused with carbon dioxide gas under pressure. This process, known as carbonation, is what gives soda water its bubbly, effervescent texture. The amount of carbon dioxide added varies between brands, but soda water generally contains 4-5 times as much carbonation as regular tap water. Apart from carbon dioxide, soda water contains no other added ingredients. It does not contain sugar, calories, artificial sweeteners, or caffeine like traditional sodas.
There are a few ways soda water can be flavored:
- Natural flavors from fruits, vegetables, herbs, etc. can be added
- Artificial flavors are added to some brands
- A squirt of fruit juice is sometimes included
However, plain, unflavored soda water contains nothing beyond carbonated water.
Is carbonation safe for babies?
The main concern with giving soda water to babies is the effect carbonation may have on their sensitive digestive systems. Babies have an underdeveloped gastrointestinal tract that is more vulnerable to gas and bloating. The American Academy of Pediatrics notes that the gut is not fully mature until around 6-8 months of age. Before this time, babies may have trouble belching or passing gas, which could lead to discomfort from the carbonation in soda water.
Some pediatricians warn that the high carbonation content can also displace air in the stomach, making babies gassy, cranky, and spit up more often. The bubbles may interfere with feeding as well. When breastfeeding or bottle feeding, babies tend to swallow more air, which then becomes trapped by the carbonation bubbles. This creates further digestive distress like painful gas, stomach cramps, and colic.
Are the ingredients in soda water safe?
Aside from the carbonation, the ingredients in soda water are safe:
- Purified water – The water used in soda water is purified through filtration and/or distillation. Impurities are removed, so it will not harm a baby’s kidneys.
- Carbon dioxide – While tough for a baby’s tummy to handle, carbon dioxide gas is naturally present in the air we breathe and the seltzer we drink. It is not toxic in the amounts added to soda water.
- Natural flavors – Flavors from real fruits, roots, and herbs do not contain harsh chemicals. But they may irritate babies if consumed in excess.
On the other hand, artificial flavors and colors may be problematic. Studies show artificial dyes like Red 40, Yellow 5, and Yellow 6 have carcinogenic effects. Babies lack the detoxifying mechanisms in the body to process these synthetic additives. Natural flavorings are a safer choice.
Risks of giving soda water too early
While the ingredients themselves are not harmful, introducing soda water too soon in a baby’s development can pose certain risks:
- Displaces nutritious breast milk or formula needed for growth
- May fill up baby’s small stomach and diminish their appetite
- Bubbles can irritate the immature digestive tract
- Causes painful gas, stomach cramps, colic, and spit up
- Artificial sweeteners and flavors may have long-term health effects
- Can lead to tooth decay once teeth come in if given regularly
Since babies under 6 months have an underdeveloped gut, stomach, and immune system, it is generally not recommended to introduce any solid foods or beverages until they reach this age.
When can babies start drinking soda water?
Most pediatricians advise against giving any soda water to babies under 6 months old. Here are the guidelines on when it may be safe to introduce soda water:
| Age | Recommendation |
|---|---|
| 0-6 months | Avoid completely |
| 6-9 months | May try a few sips if diluted with water |
| 9-12 months | 1-2 ounces maximum per day |
| Over 12 months | Up to 4 ounces per day |
Once babies reach 6 months and start solid foods, a small taste of plain soda water can be introduced. Dilute any serving with equal parts water as the bubbles may still be harsh on the stomach. Limit portions to just 1-2 ounces between 9-12 months old, and no more than 4 ounces for toddlers over a year.
Tips for giving soda water safely
If you choose to introduce soda water to your little one, keep these safety tips in mind:
- Always check with your pediatrician first
- Wait until age 6 months minimum
- Only use plain, unflavored varieties
- Dilute with equal parts water at first
- Use a bottle to control portion size
- Give very small amounts (1-2 ounces) at first
- Watch for signs of stomach upset, gas, or discomfort
- Never put soda water in a bottle or sippy cup and let baby self-feed
Introducing soda water slowly and cautiously can help minimize any issues. Discontinue use if your baby has an adverse reaction.
Healthier fizzy alternatives
If your baby enjoys bubbles, there are some healthier and safer options to consider:
- Sparkling water – Simple carbonated water without any flavoring.
- Seltzer water – Filtered sparkling water with no calories or sweeteners.
- Tonic water – Contains quinine and light flavor, so limit portions.
- Mineral water – Natural carbonation from the source.
- Water with fruit – Add a squeeze of citrus or berries to lightly flavor.
You can also substitute in some fizzy juices when your baby is older like sparkling apple cider or non-soda fruit juices. These provide more nutritional value along with the satisfying bubbles.
The bottom line
Most pediatricians agree that soda water is not recommended for babies under 6 months old. The carbonation can be difficult for their sensitive digestive systems to handle. Small amounts can be introduced after starting solid foods, but it should always be limited and given carefully under adult supervision.
While soda water itself is generally safe, its high carbonation content may cause gassiness, stomach upset, and other issues in young babies. Stick to water or milk until your baby is at least 6 months. Then use caution when first offering small portions of plain soda water diluted with water and watch for any adverse reactions.
