baby fat
C1Informal, colloquial. Often affectionate or neutral, but can be mildly disparaging depending on context.
Definition
Meaning
The temporary, soft fat deposits on a baby or very young child.
A colloquial term for mild chubbiness or residual softness, particularly on the face or body, persisting into adolescence or early adulthood, often expected to disappear with maturation. Can also refer figuratively to the softness or inexperience of a beginner or newcomer.
Linguistics
Semantic Notes
The term typically carries connotations of naturalness, temporary state, and youth. It is often used in contrast to more permanent adult weight. The possessive structure is common (e.g., 'She still has her baby fat').
Dialectal Variation
British vs American Usage
Differences
Both varieties use the term. A potential minor difference is that 'puppy fat' is a more common alternative in British English for describing adolescents.
Connotations
Similar connotations in both varieties: temporary, youthful, often non-problematic. May be used more neutrally in the US regarding young teens.
Frequency
Used in both, but possibly more frequent in American English. British English has 'puppy fat' as a stronger near-synonym for the adolescent context.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid a direct calque like "младенческий жир". Use descriptive phrases like "детская пухлость", "детская полнота", or the common phrase "щечки как у младенца" for cheeks. "Puppy fat" in UK sense can be "подростковая полнота".
Common Mistakes
- Using it to describe obesity in adults (incorrect). Treating it as a permanent condition (incorrect, it implies temporariness).
