Indeed - coughs, colds, and fever is part and parcel of growing up. It seems terrible and such a torture to parents and child, but they all have to go through it. It makes them stronger later in life.
For stuffy nose, can try things like Sterimar, which is a kind of natural salt water solution. Helps to clear the nose. Other nose prescriptive drops should be used as per doctor's advice.
For coughs, many are caused by back-drip of nasal fluids.. For this, taking the flu medicine (anti-histamine) will reduce the night coughs.
As for home remedies, you need to specify which one. And be doubly careful - i.e. plain onion soup is probably quite harmless for babies above 6 months, but onion under the feet could give terrible blisters if the child is allergic to it.
