Mouth - quivering lip and hiccups. All newborn babies' lips will look ruby red, a sign used by caregivers to know they are getting enough oxygen. It is also normal for the skin around the baby's mouth to look a little whitish - blue. This is due to the baby's skin being very fine, showing up the many veins under the skin (and is not a sign of 'wind').
Many newborn babies have tiny white cysts along the roof of their mouth or gums. These are called 'Epstein's pearls' and will go away on their own.
Your baby's bottom lip will quiver at different times. This is a normal reflex and not a response to being cold. It usually happens in response to being stimulated by sudden noises, being moved, changing your baby's clothes or the way they are lying.
Most babies get the hiccups (often spelt as 'hiccoughs'), and many women will notice their baby hiccupping during the pregnancy. We don't really know why babies get the hiccups, but we think they may be a way for the baby's diaphragm (a muscle under the lungs in the abdomen necessary for breathing) to becoming stronger by contracting suddenly.
Babies usually are unperturbed by hiccups and breast fed babies will hiccup more than babies who are bottle-fed (we don't know why?). Hiccups will usually go away on their own, or feeding your baby could help them stop.
