Begins to control hand and feet actions, but these movements are not fine-tuned.Better eye-muscle control allows the infant to track objects.Tonic neck response, left arm extends when infant gazes to the left, while right arm and leg flex inward, and vice versa.Stepping and walking, takes brisk steps when both feet are placed on a surface, with body supported.Rooting and sucking, turns head in search of nipple when cheek is touched and begins to suck when nipple touches lips.Plantar grasp, infant flexes the toes and forefoot.Placing, leg extends when sole of foot is touched.Palmar hand grasp, infant closes hand and "grips" your finger.Moro reflex (startle reflex), extends arms then bends and pulls them in toward body with a brief cry often triggered by loud sounds or sudden movements.Babinski reflex, toes fan outward when sole of foot is stroked.Neck is unable to support the head when the infant is pulled to a sitting position.Can lift and turn their head when lying on their back.For example, sucking comes before sitting, which comes before walking. Physical, such as fine motor skills (holding a spoon, pincer grasp) and gross motor skills (head control, sitting, and walking)Īn infant's physical development begins at the head, then moves to other parts of the body.Infant development is most often divided into the following areas:
