Morphology

in + diaper

The meaning 'wearing diapers' is directly and literally derived from combining 'in' (indicating being clothed or contained within) with 'diaper' (the garment), so a learner who knows both words will readily infer the MWE. This construction follows common clothing/state patterns in English (e.g., 'in pajamas') and is cross-linguistically transparent, making it immediately comprehensible at B1.

Etymology

In diapers comes from the simple image of a baby wearing diapers to stay clean and dry. Because only babies wear diapers, saying someone is in diapers means they are 'very young' or 'not yet toilet trained'.
