'jollied along' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Perhaps there's an association between them I don't understand?

'child always heading off bored' is the wordplay.
'child' becomes 'ch'.
'always' becomes 'eer' (poetic way of saying ever).
'heading off' means to remove the first letter.
'bored' becomes 'fedup' (I've seen this before).
'fedup' with its initial letter removed is 'edup'.
'ch'+'eer'+'edup'='CHEERED UP'
