British vs American Usage
Differences
In the UK, 'infant' is commonly used in the educational term 'infant school' (ages 4–7). In the US, this term is not used for schooling; 'preschool' or 'kindergarten' are preferred. Legally, the age defining an 'infant' varies by jurisdiction.
Connotations
Both varieties share core connotations of extreme youth and dependency. The UK usage has an additional, neutral institutional connotation through education.
Frequency
Slightly more frequent in UK English due to its specific educational context. In both varieties, 'baby' is more common in everyday speech.
