garland

I'm a little stuck... Click here to teach me more about this clue!

'wreath' is the definition.
('garland' can be a synonym of 'wreath')

'left kid upside down' is the wordplay.
'left kid upside' becomes 'gar' (I can't justify this - if you can you should give a lot more credence to this answer).
'down' becomes 'land' ('land' can be a synonym of 'down').
'gar'+'land'='GARLAND'

'with' is the link.

Can you help me to learn more?
