Below is a list of primitive reflexes that infants are born with. Most of these disappear within the first year of life. It is likely that these reflect vestiges from our evolutionary past.
||The mouth opens in response to pressure on the palms.
||The baby turns toward the stimulus if the cheek is stroked. This prepares the child for nursing.

||The feet make stepping movements when the infant is held upright with the feet touching a flat surface below.
||Babies wave their arms and legs and hold their breath when underwater.
