Newborn reflexes
When awake they are constantly experiencing new stimuli from which they learn how to respond. The behaviour of the newborn baby cycles between being asleep, hungry then fully alert. These behaviours are supported by a number of reflex responses that can be triggered in different situations: Some of the reflexes will disappear as the baby grows. For example, the startle reflex disappears around 6 months of age.

Rooting
Between 0-3 months of age babies learn to turn when someone speaks to them, and smile when they hear a voice. In fact, they seem to recognise familiar voices, and will quieten to the sound of that voice. Babies under three months will also stop their activity and attend closely to the sound of an unfamiliar voice. They will often respond to comforting tones whether the voice is familiar or not.
They listen to the speech of those close to them, and startle or cry if there is an unexpected noise. Loud noises wake them, and they become "still" in response to new sounds.
Grasping
If the baby's palm is stroked, they will make a fist around the finger doing the stroking. This is known as the grasping reflex.
Startle (Moro)
A Startle, or Moro reflex is triggered when the baby is either moved suddenly or if a loud noise, such as a clap, occurs suddenly. The reflex is to arch the back and extend the arms, fingers and legs. The head also falls back.
Walking
Holding the baby such that their feet touch the floor, will induce a walking reflex. The baby will automatically make step-like motions with alternate feet.
