Final answer:
A hypothetical baby boy named Liam exhibits a series of developmental milestones during his first year, e.g., smiling at two months, sitting and recognizing colors by six months, babbling by ten months, and potentially walking and understanding commands by twelve months. His growth includes physical and cognitive developments that can vary among infants.
Step-by-step explanation:
Infant Development Milestones
Let's consider a hypothetical baby boy named Liam and track his developmental milestones over the first twelve months of his life, which are critical for his growth both physically and cognitively.
Birth to One Year
Two Months: Liam can hold his head erect and steady when held upright, and he starts cooing and babbling at familiar faces. He also begins to smile at his parents.Six Months: By now, Liam is able to pick up objects and transfer them between hands. He pulls himself into a sitting position, notices colors, and may display stranger anxiety. His vision is almost as acute as an adult's.Ten Months: As he approaches the end of his first year, Liam works on standing while holding onto something, watches where toys go when dropped, and starts to babble words like 'mama' or 'dada'.Twelve Months: Liam may start walking with assistance, understands simple commands, waves goodbye, and shows cooperation during dressing.
During the first year, babies like Liam grow very quickly, doubling in length and tripling in weight. Cognitive developments such as understanding object permanence and responding to verbal requests also manifest during this time. The progression of these milestones may vary among infants but are essential markers of typical development.
