Sacked Brent-alike, infantile crawler (5-5)

I believe the answer is:

ankle-biter

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

'infantile crawler' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'sacked brent-alike' is the wordplay.
'sacked' is an anagram indicator (sack can mean to destroy).
'brent'+'alike'='brentalike'
'brentalike' with letters rearranged gives 'ANKLE-BITER'.

Can you help me to learn more?
