The nurse observes a 10-month-old infant using her index finger and thumb to pick up pieces of cereal.
What does this behavior indicate the infant has developed?

Choice A rationale:

Parallel play is a stage of play commonly seen in toddlers and young children. During parallel play, children play alongside each other, engaging in similar activities, but they do not interact directly with one another. In this scenario, where the toddlers are playing with dolls side by side without interacting, it aligns with the characteristics of parallel play. This type of play is a normal developmental stage and helps children learn from each other and develop social skills.

Choice B rationale:

Solitary play refers to a type of play where a child plays alone without interacting with others. In this case, the children are not playing alone; they are playing alongside each other, making solitary play an incorrect choice.

Choice C rationale:

Cooperative play involves children playing together in a group with a common goal or activity, such as building a sandcastle together. In this scenario, the children are not collaborating on a common task; they are playing individually alongside each other. Therefore, cooperative play is not the correct choice.

Choice D rationale:

Associative play occurs when children play alongside each other and interact with one another but do not have a shared goal or activity. Since the children in this scenario are not interacting with each other, associative play is not the correct choice.

Choice A rationale: Toddlers who can stay dry for about 2 hours demonstrate bladder capacity and control, indicating readiness for toilet training initiation and successful bladder training outcomes.

Choice B rationale: Three hours of dryness exceeds typical toddler bladder capacity; most children cannot consistently achieve this duration until later developmental stages, making it less reliable for readiness assessment.

Choice C rationale: Four hours of dryness is uncommon in toddlers; bladder control at this level usually develops in preschool years, not during early toilet training readiness evaluation.

Choice D rationale: Five hours of dryness is unrealistic for toddlers; such extended control reflects older child bladder maturity, not appropriate for determining readiness in early toilet training.
