If a baby has a stuffy nose, you can try using garlic slices in hot water or brown sugar water to relieve the congestion. At the same time, pay attention to keeping the baby warm. You can cut a piece of scallion and place it under the baby’s nose for them to sniff, as the pungent smell of the scallion can also relieve the stuffy nose. Additionally, be especially vigilant about keeping warm during cold weather and drink plenty of plain water. It is recommended to increase the baby’s intake of lactoferrin to boost immunity and prevent respiratory bacterial infections.
