This is a Christmas book and it follows three mice who are brothers. They're named after spices (if my memory serves me correctly, Nutmeg, Cinnamon, and Ginger). They're trying to find a Christmas present for their mother and she sings them a lullaby. This is all of the information that I can remember, but I am a senior in high school and I read it roughly 10 years ago.
The only thing my search came up with was this series by Emily Bearn:

None of the titles ring a bell for me, but thank you for coming up with this series! There seem to be a lot of books about mice and Christmas, so I knew it would be rough to attempt to find it.
Hi! I found the book FINALLY! In case anybody else wants to know, it’s The Micest Gift of All by Celeste Joyner Hutchins.
