I believe the answer is:

infanthood

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

'early stage' is the definition.
The definition suggests a singular noun which matches the answer.

'sketchy info to hand?' is the wordplay.
'info to hand' can be anagrammed to 'INFANTHOOD'.
But, I am not clear how this is indicated.

'it's' is the link.
