Saline drops and gentle suctioning are the safest, most effective tools for relieving a baby’s congestion. Most infant stuffiness clears on its own within a week or two, but in the meantime, a few simple interventions can help your baby breathe, eat, and sleep more comfortably. No medication is needed for typical nasal congestion in babies, and most over-the-counter cold medicines are actually unsafe for young children.
Saline Drops and Suctioning
Plain saline nasal drops (salt water without any added medication) are the cornerstone of congestion relief for babies. Place two to four drops into each nostril while your baby is lying on their back, then hold their head back for about a minute. This gives the saline time to thin the mucus so it’s easier to remove. You can buy saline drops at any pharmacy, or make your own with sterile, distilled, or previously boiled water and a small amount of salt.
After the saline has had a minute to work, use a bulb syringe or nasal aspirator to suction out the loosened mucus. The technique matters: squeeze the air out of the bulb before you place the tip in your baby’s nostril, then gently release the bulb to create suction. If you skip that step and squeeze while the tip is inside the nose, you’ll push a puff of air into the nostril that can drive mucus deeper. After suctioning one side, squeeze the mucus onto a tissue, then repeat on the other nostril.
Limit suctioning to no more than four times a day. Doing it too frequently can irritate the delicate lining inside your baby’s nose, which creates swelling and makes congestion worse. Timing it about 15 minutes before feedings or naps tends to give the best results, since those are the moments when clear breathing matters most. Wash the bulb syringe and any droppers after every use.
Cool Mist Humidifiers
Adding moisture to the air helps keep nasal passages from drying out and makes mucus easier for your baby to pass. A cool mist humidifier in your baby’s room, especially during sleep, can make a noticeable difference. Always choose cool mist over warm mist for children. Both types humidify the air equally well (the vapor reaches the same temperature by the time it enters the airways), but warm mist humidifiers and steam vaporizers pose a burn risk if your baby gets close or if hot water spills.
Humidifiers need daily maintenance. Empty the tank and dry all surfaces every day to prevent mold and bacteria from growing inside, which would defeat the purpose entirely.
Steam From a Hot Shower
If you don’t have a humidifier, you can create a similar effect by running a hot shower with the bathroom door closed and sitting in the steamy room with your baby for 10 to 15 minutes. You’re not putting your baby in the shower. Just let the warm, humid air do the work of loosening mucus. This can be especially helpful right before a suctioning session or before bed.
Why Cold Medicine Is Off-Limits
The FDA does not recommend over-the-counter cough and cold medicines for children under two years old. These products can cause serious side effects in infants, including dangerously slowed breathing. Manufacturers now voluntarily label most of these medicines with “do not use in children under 4 years of age.” This includes decongestants, cough suppressants, and combination cold remedies. There is no safe dose of these products for a baby, no matter how small an amount you might consider giving.
Honey is another remedy that’s completely off-limits for babies under 12 months. While honey can soothe coughs in older children, it carries spores of a bacterium that can colonize an infant’s intestine and produce a dangerous toxin, causing infant botulism. This applies to honey in any form, including honey-containing products.
Fever and Pain Relief
If your baby’s congestion comes with a fever, acetaminophen is an option for infants. Ibuprofen should not be given to babies under six months old. For either medication, the correct dose is based on your baby’s weight, not their age, so check with your pediatrician or pharmacist if you’re unsure. These medications treat fever and discomfort but won’t relieve the congestion itself.
Sleep Safety During Congestion
It’s tempting to prop up one end of your baby’s crib to help with drainage, but this goes against current safety guidelines. The American Academy of Pediatrics recommends that babies always sleep on a firm, flat surface. No incline, no wedge, no pillow under the mattress. Inclined sleep surfaces increase the risk of suffocation and sleep-related infant death. The same goes for placing pillows, rolled towels, or blankets in the crib. A stuffy nose is uncomfortable, but a flat, clear crib is non-negotiable for safe sleep.
Instead of elevating the crib, do a saline-and-suction session about 15 minutes before putting your baby down. Running a cool mist humidifier nearby can also help keep their breathing comfortable through the night.
Signs of Breathing Trouble
Most nasal congestion in babies is caused by a common virus and resolves without complications. But congestion can occasionally signal something more serious, especially in very young infants whose airways are tiny. Watch for these physical signs of respiratory distress:
- Nasal flaring: the nostrils visibly spread open with each breath, indicating your baby is working harder than normal to pull in air.
- Retractions: the skin pulls inward just below the neck, under the breastbone, or between the ribs during each breath. This means your baby is using extra effort to expand their lungs.
- Fast breathing: a noticeably increased breathing rate, especially when your baby is at rest.
- Color changes: bluish tint around the lips or fingertips.
- Difficulty feeding: refusing to eat or being unable to suck because they can’t coordinate breathing and swallowing.
Any of these signs warrants prompt medical attention. For babies under three months, even a low fever alongside congestion is worth a call to your pediatrician, since young infants can deteriorate quickly from infections that would be routine in an older child.
