Bit tired, some kids doze, ultimately getting off with these? (7,7)

'these?' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'bit tired some kids doze ultimately getting off' is the wordplay.
'ultimately' says to take the final letters.
'getting off' indicates an anagram (off can mean inaccurate or wrong).
The last letters of 'kids doze' are 'se'.
'bit'+'tired'+'some'+'se'='bittiredsomese'
'bittiredsomese' is an anagram of 'BEDTIME STORIES'.

'with' is the link.
