I do believe this is the sequel to Your Birthday was the Best!  I loved that book.  I still find this book cute and loveable.  A family of cockroaches hitch a ride to school in their human friend’s backpack and school shenanigans ensue.  I do have a problem though.  Most kids seen with cockroaches coming out of their backpacks would be a cause for concern and could have dire consequences.  It would appear that the family needs help and others might get involved.  So while I take this book with a grain of salt and love it for what it is, I think many others may have a problem as these cockroaches could be seen as unhealthy or as family that is not taking care of their child.
