Child with me picked up an emblem (5)
I believe the answer is:
totem
'an emblem' is the definition.
(totem is a kind of emblem)
'child with me picked up' is the wordplay.
'child' becomes 'tot' (tot is a kind of child).
'with' says to put letters next to each other.
'picked up' is a reversal indicator.
'me' back-to-front is 'em'.
'tot'+'em'='TOTEM'
(Other definitions for totem that I've seen before include "Emblem of a clan" , "Revered symbol" , "Venerated emblem" , "Symbol, emblem" , "Spiritually significant emblem" .)
