If your one-year-old child has a cold, it is important to encourage them to drink fluids to help with throat secretions. This can help alleviate congestion and nasal drainage. Using a saline solution like Hydrasense or Salinex can also help reduce congestion and prevent secretions from dripping down the throat. It is recommended to do this multiple times a day, as often as needed. Additionally, using a nasal aspirator can help remove excess mucus from the nose. These steps can help your child feel more comfortable and aid in their recovery from the cold.
