Babies might quiver their bottom lip because they want attention, or it could be an early sign of neurological problems.

Also known as labial tremor, the quivering of the lower lip is a type of muscular spasm that appears when the baby cries. This habit is one that usually disappears when the baby reaches six months.

It can also happen when they are hungry, tired, or are suffering from colic.

The reasons for this gesture are unclear but there are two main theories. It has been suggested that babies perform this action to get attention if they feel ignored.

Another hypothesis suggests that young children do it to calm themselves down by entertaining themselves with what they see in front of them.

According to some experts if the habit persists beyond six months it could be a sign of neurological problems such as cerebral palsy.

This action might also happen because of an imbalance in neurotransmitters, which regulate mood and behavior and this can lead to autistic or hyperactive disorder.

If you notice your baby quivering his lip you should consult a doctor who will examine him very thoroughly. If there is no apparent cause for it you may be able to treat the condition at home by massaging your child’s gums with an index finger or using any kind of distraction.

such as giving him toys that make noise or fun things like singing games.
