Andrew Lost in the Kitchen #3 by J. C. Greenburg*

My second grader read this book to himself.  This is his review.
In book #1 Andrew shrinks himself, his cousin Judy and his robot Thudd (his best friend).
He is trying back to the Atom Sucker (which shrunk him) to become normal size again before 8:01.
This book they are lost in the kitchen.  They encounter a cockroach.  Andrew almost is put into a refrigerator.
*Highly recommend.
