My 20 days baby daughter having a cold and unable to sleep for long hours. Pl guide what to do

A. Put put nasal drops into the nose of your child every 4 to 6 hours which is going to help in easy breathing will help in opening up the nasal passage along with that you can give steam to the child indirectly and also put a pillow under the head because it’s easier for them to breathe in an elevated position
