Breathing problems that get worse during coughing, crying, feeding or colds. High-pitched sound during breathing (stridor). High-pitched cough. Rattling noise or wheezing with breathing. [4]
Sound intensity: Patients show a large variability in sound intensity ranging from 40 dB to 120 dB. [15] In addition, sounds can also be long and soft as well as short and loud. [7] Onset time of the noise during the night: The ISCD-2 established latency of noises after falling asleep ranging from 2 to 6 h. [11]
Overstimulation may be a contributing factor to infant crying and that periods of active crying might serve the purpose of discharging overstimulation and helping the baby's nervous system regain homeostasis. [10] [11] Although crying is an infant's mode of communication, it is not limited to a monotonous sound.
Crying is critical to when a baby is first born. Their ability to cry upon delivery signals they can breathe on their own and reflects they have successfully adapted to life outside the womb.

Transient tachypnea of the newborn is a respiratory problem that can be seen in the newborn shortly after delivery. It is caused by retained fetal lung fluid due to impaired clearance mechanisms. [1] It is the most common cause of respiratory distress in term neonates.
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

Although this is a congenital lesion, airway sounds typically begin at age 4–6 weeks. Until that age, inspiratory flow rates may not be high enough to generate the sounds. Symptoms typically peak at age 6–8 months and remit by age 2 years. Late-onset laryngomalacia may be a distinct entity, which can present after age of 2 years.
