'little 'un' is the definition.
I can't judge whether this definition defines the answer.

'beginning to teethe left in care of stranger' is the wordplay.
'beginning to' suggests taking the first letters.
'left' becomes 'l' (common abbreviation).
'in care of' is an insertion indicator.
'stranger' becomes 'odder' (more odd).
The initial letter of 'teethe' is 't'.
'l' placed into 'odder' is 'oddler'.
't'+'oddler'='TODDLER'
