[bernardina]

Isn't to put sth to rest more relevant in c)?

Anyway, in Greek there's no valid idiom covering all three cases. In the first is just έβαλε το παιδί για ύπνο. Το έστειλε στο δωμάτιό του for the punishment.

Τέλος και τω Θεώ δόξα used to be a very popular phrase to find at the end of an essay once upon a time. As well as Τυπωθήτω! (Let it be printed!) Now is just Ουφ, επιτέλους, τελειώσαμε!
