Question

Arrange these motor milestones during the infancy in the order that they are accomplished
A. Walks alone
B. Crawls
C. Rolls over
D. Stand alone
E. Sits alone
Choose the correct answer from the option given below:

• A. C, E, B, D, A
• B. D, C, B, A, E
• C. E, C, D, B, A
• D. A, C, E, D, B

Hint:

Infant Motor Milestone Timeline: Roll over ($4\text{m}$) $\rightarrow$ Sit alone ($6-7\text{m}$) $\rightarrow$ Crawl ($8-9\text{m}$) $\rightarrow$ Stand alone ($11\text{m}$) $\rightarrow$ Walk alone ($12\text{m}$).

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
Cephalocaudal and proximodistal infant gross motor milestone sequence during the first year of life.

Step 2: Detailed Explanation:
Standard chronological progression of infant gross motor milestones:
1. C. Rolls over: $\approx 3 - 5\text{ months}$ (from side to back/stomach).
2. E. Sits alone without support: $\approx 6 - 7\text{ months}$.
3. B. Crawls on hands and knees: $\approx 8 - 9\text{ months}$.
4. D. Stands alone without support: $\approx 10 - 11\text{ months}$.
5. A. Walks alone independently: $\approx 12 - 14\text{ months}$.
Sequence: C $\rightarrow$ E $\rightarrow$ B $\rightarrow$ D $\rightarrow$ A.

Step 3: Final Answer:
Thus, the correct developmental sequence is C, E, B, D, A, corresponding to option (A).
