Seven-month-old baby has a cold, cough and runny nose. If the baby has a clear nose, it is a sign of cold. You can boil a cup of water with a small half spoon of brown sugar and a piece of ginger for your child to drink. At the same time, you should soak your feet in warm water, the water is not hot to add water properly, you need to soak for 20 minutes, and then give your child more clothes and massage the two feet with your fingers. If there is sweating, do not rush to undress, let him slowly eliminate sweat, start feeding plain water, do not rush to feed too much, the main thing is to feed diligently on the line, to urinate more. In addition, use a head of garlic and some rock sugar to boil water, boil the water for 20 minutes on low heat, then give it to the child after it is warm and cool, feed it slowly and let the child urinate more, even for a few days, 50ml each time, in the morning on an empty stomach and at night before going to bed. Garlic water is for treating wind-cold colds and also coughs, and it is particularly effective. If there is still snot the next day, you can do it again as you did the day before, and your child should not get cold at night, and the temperature of the hands and feet is just right, hot or cold to adjust the bedding.
