Child's pouch found in rubbish dump by Swede on vacation (8)

'child's' is the definition.
(pappoose is a kind of child)

'rubbish dump by swede on vacation' is the wordplay.
'rubbish' becomes 'pap' (pap can mean rubbish or trivia).
'dump by' becomes 'poo' (I can't explain this - if you can you should believe this answer much more).
'on vacation' says to hollow out the word (remove centre letters) (after the inside letters have vacated the word).
'swede' with its middle taken out is 'se'.
'pap'+'poo'+'se'='PAPPOOSE'

'pouch found in' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.

Can you help me to learn more?
