Open-Cup Drinking Development: A Review of the Literature

Area of Science:

• Pediatric feeding development
• Infant motor skills
• Childhood cognitive development

Background:

• Limited research exists on factors influencing open-cup drinking progression in typically developing infants and toddlers.
• Clinicians lack a robust framework for addressing delays in open-cup drinking.
• Understanding developmental milestones is crucial for early intervention.

Purpose of the Study:

• To systematically review and synthesize existing literature on sensorimotor and cognitive factors essential for open-cup drinking.
• To provide a foundational understanding for clinicians working with children experiencing feeding delays.
• To bridge knowledge gaps in the developmental progression of independent drinking.

Main Methods:

• Literature search across various disciplines including pediatrics, occupational therapy, and developmental psychology.
• Systematic collation of studies focusing on sensorimotor and cognitive prerequisites for drinking.
• Thematic analysis of identified factors contributing to successful open-cup drinking.

Main Results:

• Key sensorimotor components include oral motor control, postural stability, and hand-to-mouth coordination.
• Cognitive elements such as attention, imitation, and understanding cause-and-effect are vital.
• Developmental progression is influenced by the interplay between these sensorimotor and cognitive abilities.

Conclusions:

• Successful open-cup drinking relies on integrated sensorimotor and cognitive development.
• Further research is needed to establish normative data and specific intervention strategies.
• This review provides a basis for clinical assessment and targeted interventions for feeding difficulties.
