You can make safe saline drops for your baby at home with just non-iodized salt, baking soda, and sterilized water. The whole process takes about five minutes, and the American Academy of Pediatrics confirms that homemade saline drops are a fine option for clearing a stuffy baby nose. Getting the ratio and water safety right is what matters most.
The Recipe
Start by making a dry mix you can keep on hand. Combine 3 teaspoons of non-iodized salt with 1 teaspoon of baking soda in a small airtight container. This dry mixture stays good indefinitely.
When you’re ready to make a batch of drops, add half a teaspoon of the dry mix to 4 ounces (half a cup) of lukewarm sterilized water. Stir until fully dissolved. That’s it. The baking soda acts as a buffer that prevents the solution from stinging your baby’s nose.
Why the Salt Type Matters
Use pickling salt, canning salt, or any salt labeled “non-iodized” and “pure.” Regular table salt contains iodine and anti-caking agents that can irritate delicate nasal tissue, especially in an infant. The ingredient list on the salt container should ideally say only “sodium chloride.” Kosher salt works in a pinch, but check the label for additives first.
Getting the Water Right
This is the single most important safety step. Never use tap water straight from the faucet. Water that hasn’t been sterilized can contain microorganisms, including a rare but dangerous amoeba called Naegleria fowleri, that are harmless to swallow but potentially harmful when introduced into nasal passages.
You have two safe options:
- Store-bought distilled or sterile water. Look for bottles explicitly labeled “distilled” or “sterile.”
- Boiled tap water. Bring water to a rolling boil for one full minute (three minutes if you live above 6,500 feet elevation), then let it cool to lukewarm before mixing.
Storage and Shelf Life
Homemade saline doesn’t contain preservatives, so bacteria will eventually grow in it. Store your prepared solution in a clean, covered container in the refrigerator and discard any unused portion after three days. Making small batches (4 ounces at a time) helps minimize waste. Let refrigerated drops warm to room temperature or hold the container in your hands for a minute before using them, since cold drops in a baby’s nose are startling and uncomfortable.
How to Give Your Baby Saline Drops
Lay your baby on their back. Using a clean dropper, place 3 to 4 drops into each nostril. Your baby will probably sneeze, squirm, or fuss briefly. That’s normal. Hold them with their head tilted slightly back for about a minute to give the saline time to loosen and thin the mucus.
After a minute, you can use a bulb syringe to gently suction out the loosened mucus. Squeeze all the air out of the bulb first, then gently place the tip just inside one nostril. Release the bulb slowly to draw out mucus. Squeeze the contents onto a tissue, then repeat on the other side. Wipe around the nose gently with a soft tissue to prevent skin irritation from the moisture.
A few practical tips that make a real difference: do this about 15 minutes before feeding or nap time so your baby can eat and sleep more comfortably. Limit suctioning to no more than four times a day. More frequent suctioning can irritate and swell the nasal lining, which makes congestion worse rather than better. The saline drops themselves can be used more often than that, but aggressive suctioning is what causes problems.
What Happens if the Ratio Is Off
If you use too much salt, the solution becomes hypertonic, meaning it’s saltier than your baby’s body fluids. This can sting and irritate the nasal lining. Research on infants shows that concentrations above roughly 3% saline start to cause more throat and nasal irritation without offering extra benefit for clearing mucus. The recipe above produces a solution close to 0.9%, which matches the salt concentration of your body’s own fluids and feels comfortable going in.
Too little salt is less of a concern for safety but can also cause mild stinging, since plain water without any salt irritates mucous membranes in its own way. Sticking close to the recommended ratio keeps things comfortable.
Homemade vs. Store-Bought Drops
Commercial saline drops (like Little Remedies or Simply Saline) contain the same basic ingredients: saline and sometimes a preservative to extend shelf life. Their main advantage is convenience and a longer expiration date. Their main disadvantage is cost, since you’ll go through them quickly during a cold. Homemade drops work just as well if you follow the water safety and storage guidelines above. Just make sure, if you buy commercial drops, that they contain only saline and no added medication like decongestants, which are not safe for infants.
