What is the earliest age at which the infant should be able to walk independently?

Choice A rationale:

Sending the child to his room for 30 minutes is not an appropriate intervention for dealing with occasional aggression in a 4-year-old child. A 30-minute timeout is excessively long for a young child and may not effectively address the behavior.

Choice B rationale:

Having the child take a time-out in the corner for 4 minutes is the most appropriate intervention. Time-outs are an effective method for addressing undesirable behaviors in children. Four minutes is an appropriate duration for a 4-year-old, and it allows the child to calm down and reflect on their behavior.

Choice C rationale:

Spanking the child at the time of the incident is not a recommended intervention for managing aggression in children. Physical punishment can be harmful and is generally discouraged in favor of more positive and effective disciplinary techniques.

Choice D rationale:

Taking away television privileges for the day may not be the most effective immediate response to occasional aggression in a 4-year-old. While consequences can be an appropriate part of discipline, they should be proportionate to the behavior, and it's often more effective to use a short-term time-out to address the immediate issue. For a lethargic 10-month-old infant, the best action is to handle the infant slowly and gently (Choice D). To support a toddler's desire to self-feed, it's advisable to offer foods that are varied and colorful and provide finger foods (Choices A and D). When dealing with occasional aggression in a 4-year-old child, the most appropriate intervention is to have the child take a time-out in the corner for 4 minutes (Choice B). .

Choice A rationale:

Infants should be able to walk independently at the age of 8 to 10 months is the correct choice. This is the typical age range when most infants start taking their first independent steps.

Choice B rationale:

12 to 15 months is within the expected range, but it's a bit later than the earliest age for independent walking. It's still considered a normal developmental range.

Choice C rationale:

18 to 21 months is a more extended range for independent walking, and it may raise some concerns if a child has not started walking independently by 21 months. This range represents a delay in motor development.

Choice D rationale:

15 to 18 months is also within the expected range for independent walking, but it's not the earliest age. It's still considered a normal developmental milestone.
