Notice later what those who take care of others do (9)

I believe the answer is:

lookafter

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

'those who take care of others do' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'notice later' is the wordplay.
'notice' becomes 'look' (I can't justify this - if you can you should believe this answer much more).
'later' becomes 'after' (I've seen this before).
'look'+'after'='LOOKAFTER'

'what' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish News.
