Good cereal for kids and their parents? (5)

I believe the answer is:

goats

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

'kids and their parents?' is the definition.
I can't judge whether this defines the answer.

'good cereal' is the wordplay.
'good' becomes 'g' (abbreviation).
'cereal' becomes 'oats' (type of cereal).
'g'+'oats'='GOATS'

'for' acts as a link.

Can you help me to learn more?

(Another definition for goats that I've seen is " ruminants".)
