According to the Denver Developmental Screening Test, which is a widely used screening test to detect problems in the development of children from birth to six years of age, a child should be able use use their thumb and finger to grasp or pinch a piece of cereal at eight months of age. After one year of age the child should be able to walk, scribble, make a tower of two cubes, and kick a ball. 

The question describes the Babinski reflex. It is present at birth and will continue until the infant reaches approximately two years of age.

The correct answer is “rooting and cheeks.” The rooting reflex involves the infant turning its head after its cheek is stimulated. The Moro reflex is also called the startle reflex because the infant extends its arms and limbs after being startled. The Babinski reflex happens when an infant's foot is rubbed and its toes fan out. Last, the grasping reflex occurs when a finger or object is put in an infant's hand. 

Infants are expected to be able to lift their head, smile socially, and coo between the age of 1-3 months. Infants begin to crawl between 7-11 months. Infants start walking between 12-15 months. Lastly, infants can begin to sit unassisted between 4-6 months. 

An infant is not expected to be able to crawl until 7-11 months, where they are also expected to show stranger anxiety, use gestures, and imitate sounds. The rest of the listed behaviors are typical of an infant between 4-6 months. 

An infant is expected to be able to walk unassisted, can show separation anxiety, and say their first words (not necessarily 5 new words) at 12-15 months. By 1.5 years (18 months) of age, a toddler is expected to say around 10 words and throw a ball. A child is expected to be able to copy a square around age 5.

At 1.5 years of age, a child is expected to be able to stack 3 blocks and use about 10 individual words. A toddler can say around 250 words by the age of 2. Secondly, a child is expected to be able to copy a circle by the age of 3. Lastly, a child is expected to catch a ball with two hands by the age of 5.

A child normally, if applicable, begins having imaginary companions at 4 years of age. During this time they are also expected to be able to hop on one foot, copy a cross, play cooperatively with other children, and express themselves clearly verbally. A child is not expected to be able to copy a square until age 5. Children learn to tie shoelaces and read by the age of 6. 

A child is expected to be able to catch a ball with both hands by 5 years. During this time they are also expected to be able to copy a square, skip using both feet, and may show romantic feelings for the opposite sex (4-5 years of age). At the age of 2, most children can kick a ball. At 3 years, most children can climb stairs using alternate feet. At the age of 4, children are expected to be able to catch a ball with their arms. 

A child is expected to be able to draw a cross by the age of 4. A square is typically copied by 5 years, and a triangle by 6 years. The ability to copy a diamond is not expected until the age of 7.
