My daughter is having cough, cold and blocking chest, recommend me some home remedies for her. She is 2.8 years old

Hi, Give her steam. Sit with her, or hold her in your arms and help her in taking steam. Feed her soup. Make kadha of her. Take one cup of water and add ginger, clove in it. You can also add basil. Boil the water till one-fourth of it is left. Then cool it down and feed this concoction to your baby there or four times a day. This should bring relief. Also can massage her chest and back with desi ghee. Can apply little on nose as well.
