The Chronicles of Sheldon Mayer's Sugar & Spike
Sugar & Spike #27 
Reprints: The Best of DC #47 
Dedication: Mrs. Marjorie Lane (age 21 plus), California
Spike is a bit of a pest while his mother tries to talk to Sugar's mother. Sugar's mother suggests something that she learned from the baby-book that works for Sugar, letting the kids play as giants in a miniature world. They decide to let Spike try it, and then Sugar explains her interpretation of the toys, and how she feels about their mothers ignoring them. All of this serves to dissipate the anger the kids have, though perhaps not for the reason the adults think.
This was among the earliest Sugar&Spike stories I read, through the 1980s digest reprint, and not really one of my favourites back then. Not sure why, but I do like it a bit better now, especially some of Sugar's dialogue when explaining things to Spike. There are also some clever bits in the art which are much easier to appreciate at full size.
Characters: Sugar, Spike, Mrs. Plumm, Mrs. Wilson
Damage: Hopefully the dolls are waterproof
Punishment: The dolls get treated harshly
Sugar's treatment of Spike: He gets a doll smacked out of his hand and yelled at a bit, but suffers much more from the coffee dumped on his head
"Whenever I'm in the mood to play with it, I make a real pest of myself until she gets it out"
