Final answer:
A baby's muscular development follows a cephalocaudal pattern, beginning at the head and progressing to the feet, with developmental milestones such as head control, sitting, crawling, and eventually walking.
Step-by-step explanation:
A baby's muscular development progresses in a pattern that is called cephalocaudal. This term describes the way infants develop motor skills from the head (cephalo) down to the feet (caudal). Motor development in infants follows a predictable sequence starting with gaining control over their heads, moving on to sitting up with assistance, then without assistance, followed by crawling, and lastly, walking.
These developmental milestones typically occur in the same order for most infants, although the exact timing may vary from one child to another. This progression represents a universal pattern recognized by health professionals and caregivers.
