Young child crying, throwing a wobbly (7)
I believe the answer is:
tottery
'a wobbly' is the definition.
(thesaurus)
'young child crying throwing' is the wordplay.
I cannot really see how this works, but
'young' could be 'y' and 'y' is present in the answer.
'child' could be 'tot' (term for a young child) and 'tot' is found within the answer.
The remaining letters 'ter' is a valid word which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for tottery that I've seen before include "Moving unsteadily" , "close to collapse" , "rocking" , "Unstable on one's feet" , "Unsteady (on one's feet)" .)
