Why does an infant's bottom lip tremble when he is eating or sucking on a pacifier? Has anyone had her infant's lip do that?

  • My son's lip did that the first 6-9 months. It's just immature nerve endings or something like that. It's completely normal and will go away in time. It's really adorable when it happens isn't it?

  • Because their nervous system isnt fully matured yet. I always thought it was cute.

  • I agree it is very cute. My mom was concerned about my son/grandson doing it, so I decided to ask the question here to see if anybody else's baby did that when he or she was six months old or younger.

  • I think it has to do with the muscles not being strong enough to do certain tasks for long periods of time. For the pacifier for example. It takes a lot of muslce power to suck on one, and the baby's lip gets tired. Which causes it to tremble, which any muscle in even an adult body would do if overused and tired. It'll lessen as they use it more and it strengthens.
