Girl feels ignored in big jewish family in the 1950's (?) U.S. little brother dies, JFICTION [s]

[Leah]

Helpful details:
-I believe this book was published recently I picked it up in the library in the new book section either this year or late last year.
-I think it has a blue cover.
-I remember the back cover saying something like..."being lost in this big family." and generally speaks about a girl who feels ignored and unheard in her big Jewish family.
-Juvenile fiction

I loved this book, but read it too quickly for the details to soak in!

Thanks in advance for any ideas of what this book might be called.

Not a blue cover, and it's set in 1936, but definitely a girl who feels lost in her big Jewish family, so maybe: Looking for Me

Thats it. I can't believe I didn't remember that there were matryoshka dolls on the cover--since I'm sure that's why I picked it up!

Thank you SO much. I have been trying to figure out what it was called for weeks.
