Consider the following statements with respect to developmental milestones at 9 months of age : 1. At this age, child develops immature pincer grasp. 2. At this age, child can say bisyllables (mama, dada, etc.). 3. At this age, child can wave bye-bye. Which of the statements given above are correct?
9 Month Milestones Analysis
This question assesses knowledge of typical developmental milestones observed in infants around 9 months of age. We need to evaluate the correctness of three specific statements.
Statement 1: Immature Pincer Grasp
Around 9 months, infants typically develop the immature pincer grasp. This milestone involves using the thumb and index finger to pick up small objects. It's considered immature because the coordination is still developing, but it's a significant step from raking or palmar grasps.
Status: Correct
Statement 2: Bisyllables Speech
Babbling progresses towards more structured sounds. By 9 months, many infants start producing bisyllables, such as "mama," "dada," or "baba," often without specifically referring to a person initially. This is a key vocalization development.
Status: Correct
Statement 3: Waving Bye-Bye
The gesture of waving bye-bye, often involving understanding the social context, typically emerges between 9 and 12 months. While some infants might start doing this consistently slightly later, it is considered a milestone that can begin appearing at 9 months.
Status: Correct
Conclusion on Milestones
Based on the analysis, all three statements accurately describe common developmental milestones observed at approximately 9 months of age.
- Statement 1: Immature pincer grasp is typical.
- Statement 2: Bisyllables like 'mama' and 'dada' are emerging.
- Statement 3: Waving bye-bye often begins around this age.
Therefore, statements 1, 2, and 3 are all correct.
