skid row

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

'squalid district' is the definition.
'skid row' can be an answer for 'district' (skid row is a kind of district). I am not certain of the 'squalid' bit.

'stops first child squabble' is the wordplay.
'stops first' becomes 's' (1st letter of 'stops').
'child' becomes 'kid' (synonyms).
'squabble' becomes 'row' (I've seen this in other clues).
's'+'kid'+'row'='SKID ROW'

'in a' is the link.

Can you help me to learn more?
