Newborns like to use their mouths in various ways. When parents notice their newborns sticking out their tongues and chewing, they might wonder if this behavior is normal. The short answer is yes; it is completely normal for newborns to stick out their tongues at this age. However, sometimes it can be a signal of something the baby wants to express or an underlying condition.

Sore throat and lymphadenopathy in the neck and tongue may or may not be dangerous. Therefore, with the initial symptoms, it is difficult to clearly distinguish between diseases such as pharyngitis, tonsillitis, etc. with potentially fatal diseases such as throat cancer.
