From Embryology
This infant is almost 3 months old.
  • The palmer grasp reflex is still present for this baby.
  • The grasp reflex is usually gone by 4 to 6 months of age for the hands and 6 to 12 months for the toes.
  • The reflex palmer grasp is gradually replaced by the voluntary activity of reaching and grasping with the hand.
