In young children, respiratory problems often occur, causing nasal congestion, runny nose, and difficulty breathing due to phlegm and mucus in the airways causing congestion. Nasal suction for children can help clear the airways, making it easier for children to breathe.

Laryngomalacia is a congenital abnormality of the laryngeal cartilage used to describe the case where the supporting tissues of the anatomical structures above the larynx, including the epiglottis and arytenoid cartilage, have not developed enough, causing these structures to fall into the child's airway, creating a wheezing sound.
