Question

Why would my 2-year-old baby chew on their lower lip?

Answer

There could be several reasons why your baby is chewing on their lower lip. Firstly, it might be because the baby is hungry, and eating can resolve this issue. Secondly, the baby may simply be accustomed to playing with their lips, a common habit among many children. In this case, you can try to redirect your baby’s attention by providing other interesting toys or items for them to chew on, instead of their lips. However, if the baby seems unaware of pain and continues to bite their lips repeatedly, causing bleeding or injuries, and has a tendency to scratch themselves, this may be a sign of autosomic recessive dysmorphic syndrome. This condition is caused by a genetic defect in xanthine-guanine phosphoribosyltransferase. Therefore, it is recommended that you observe the situation for a while. If this behavior persists and causes injury to your baby’s lips, it is imperative to take your child to a doctor for diagnosis and treatment. If the situation improves after a few days or there are no signs of bite marks, there is usually no need to worry.
