sometimes my baby's nose is blocked but there is no cough and the cold only blocks the nose and she irritates while feeding I also used nasal spray but mucus doesn't come out

A. See if there is no mucus in the nose it is not going to come out but still if you feel you have a doubt that this is mucus then you can use nasal aspirator that is going to help in clearing the mucus from the nose and it is safe to use
