I believe the answer is:
bib
'baby food catcher' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for bib that I've seen before include "Upper part of apron" , "Protective cloth; fish" , "Protective clothing - fish" , "Tempest airy spirit" , "Young diner's protector" .)
