Our baby made loud noises while breathing and we were really worried. But the solution was simple, we used a Baby Nasal Aspirator / Nose Sucker to get out the mucus that has built up inside the nose.
This is the aspirator we used:
Of course you can also buy an electric one if you want.
This saved our lives one time when the baby was breathing hard.
It removes clear fluid or mucus from baby’s nose.
We used some drops of saline solution first to make the dried mucus more fluid.
