Final answer:
Midline hand coordination develops as part of a baby's motor skills and is crucial for tasks that require both sides of the body to work together. By twelve months, infants can use this coordination to feed themselves, which requires a pincer grasp and the ability to bring their hands to the body's midline.
Step-by-step explanation:
Midline hand coordination is a skill that develops as babies grow and gain more control over their bodies. It involves the ability to bring the hands together at the body's midline and is crucial for many tasks that involve both sides of the body working together. One of the important milestones in motor development is when babies begin to pick up small objects. Typically, this skill is associated with the development of the pincer grasp, which involves using the tips of the thumb and forefinger to pick up items. Having a good midline hand coordination is essential for self-feeding, a skill that most babies start to develop by their first year.
Babies to feed themselves is the correct answer because, by twelve months, infants have developed enough motor skills and coordination to support self-feeding, even if it is still a bit messy. While midline hand coordination can certainly assist with other activities, such as rolling over, playing games, or picking up objects, the act of feeding oneself suggests a higher level of dexterity and motor control associated with bringing hands to the midline and coordinating them to convey food to the mouth.
