"The Vanderbeekers to the Rescue" by Karina Yan Glaser

This series is quickly becoming an all-time favorite for me.  In this one, their mom is danger of losing her at-home baking business, so the kids try everything they can think of to help her keep it.  But someone keeps leaving animals on their doorstep in the middle of the night -- a box of kittens, two guinea pigs, a dog, and more.  How can they find new homes for all these critters while also helping their mom pass her kitchen inspection?

I really love how these kids and their parents interact....
