YA Girl Diary book after ww2

I remember the cover being yellow and an illustration of the girl on the front on a desk with her paper. I think it may have had the word diary in the title.

It is a young adult book, mainly for girls about a girl that lives in a poor family either during or after the war I can't remember. She was given a ream of paper by her aunt I think and decides to write a diary. I think she is about 12 and is the only girl in a family of boys. I can't rember but I have a feeling she was quite mischeivous and went to a quarry when she wasn't allowed.

It was only a short book around 100-150 pages.

Thanks

Do you remember where the book was set? It could be part of the Dear America or Dear Canada series.

Zlata's Diary was set after WW2, but within a later war.

I'm not sure when A Gathering of Days was set.... oh, look. The touchstone title provides a date in the 1800s. Now we know. :)

Emily of New Moon has in common the aunt and the ream of paper and the age and a tenancy in the main character to go off and do not-entirely-safe things (although I remember a well and not a quarry in this book). But the character wrote her diary in the form of letters; not so much "Dear Diary" as "Dear (Deceased Father)" or "Dear (Me Ten Years From Now)" -- and the book was a proper novel with diary elements, not a diary by itself.

Could be I Want To Live: The Diary of a Young Girl in Stalin's Russia This is recently published, so if you read it long ago, it's not this one.

Sorry, I asked my diary expert about this and in"I want to Live", she had a diary book to write in. Still, it's a good read for young teens.
