Tot's initial reprimand for crying (7)
I believe the answer is:
tearful
'crying' is the definition.
(I've seen this before)
'tot's initial reprimand' is the wordplay.
'initial' suggests taking the first letters.
'reprimand' becomes 'earful' (earful is a kind of reprimand).
The initial letter of 'tots' is 't'.
't'+'earful'='TEARFUL'
'for' acts as a link.
(Other definitions for tearful that I've seen before include "Lachrymose, blubbering" , "emotional" , "Inclined to cry" , "Visibly upset" , "visibly distressed" .)
