The baby’s sleep ergonomics may be caused by normal phenomenon, disease factors (pharyngitis, vitamin D deficiency) and other reasons.
1. Normal phenomenon: it may be caused by dreaming, usually babies are more novel to the things in the dream, so they will make uh-uh strange sound when sleeping.
2. Disease factors:
(1) laryngitis: usually when the baby has laryngitis, when the inflammation stimulates the mucous membrane of the throat, there will be symptoms such as itching of the throat and increased secretion in the throat, which will cause the baby to make uh-oh strange sound when sleeping.
(2) Vitamin D deficiency: Vitamin D deficiency may also cause babies to make a hiccuping sound while sleeping.
There may be other reasons for babies to make strange sounds while sleeping, so parents are advised to take their babies to the doctor to find out the causes and get standardized treatments.
