My 1 month old newborn is having nasal congestion specifically early morning. Doctor has advised to use nasal drops but it still irritates her. How to know its just congestion not cold

A. Is a common thing with kids begin the child is under full speed of fan or the AC cooler is blowing direct air on their face and knows it happens so to avoid this issue avoid these temperatures and also you should put a hollow pillow under the head which helps in better breathing as a child’s head is going to be an elevated position and if you want you can also give steam indirectly
