Symbols of babies take me back (6)
I believe the answer is:
totems
'symbols' is the definition.
(I've seen this in another clue)
'babies take me back' is the wordplay.
'babies' becomes 'tots' (I've seen this in another clue).
'take' is an insertion indicator.
'back' is a reversal indicator.
'me' backwards is 'em'.
'tots' enclosing 'em' is 'TOTEMS'.
'of' is the link.
(Other definitions for totems that I've seen before include "Poles" , "Natural objects adopted as emblems" , "Signs" , "Emblems once adopted by native Americans, seen on pole" , "family emblems" .)
