Bringing up with provision of internal liquid feast (13)

I believe the answer is:

breastfeeding

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

'bringing up with provision of internal liquid feast' is the definition.
I can't tell whether this defines the answer.

'bringing up with provision of internal liquid feast' is the wordplay.
'bringing up' becomes 'breeding' (eg bringing up children).
'with provision of internal' is an insertion indicator.
'liquid' indicates anagramming the letters.
'feast' anagrammed gives 'astfe'.
'breeding' enclosing 'astfe' is 'BREASTFEEDING'.

Can you help me to learn more?

(Another definition for breastfeeding that I've seen is " Providing (a baby) with milk".)

I've seen this clue in The Telegraph.
