I read this broken up as four stories for my Beverly Cleary Author Study. This book is a collection of the Janet and Jimmy stories. It seems like an Easy Reader story on its own, but Google shows they were kind of a picture book/Easy Reader hybrid. I like them as a collection because I think they work well as a beginner chapter book. The twins are only four, though, so I can see the reasoning behind making it a picture book parents would read to their four-year-olds.
The Real Hole: Janet loves to play pretend, but Jimmy loves things that are real. When he digs a real hole, Janet wants to pretend it's a nest or a fishing pond. Jimmy doesn't like that, but he doesn't know what he could use the hole for.
This book is pretty simple but it's fun and light-hearted, and I think kids would love it because it's definitely how kids act.
Two Dog Biscuits: This was a cute Janet and Jimmy story. A neighbor hives them each a dog biscuit (though... why?) and their mother is worried they'll eat them. Then she gets sick of seeing the dog biscuits everywhere around the house and finding them in pockets. Their mother takes them on a walk so the twins can give their biscuits to dogs they meet along the way. But one dog is too big, one is too mean, one too loud... Will the twins ever find a critter to enjoy their biscuits?
The Growing-Up Feet: Janet and Jimmy's mother thinks they've outgrown their shoes, so they all go on an adventure to the shoe store. Janet and Jimmy are excited to get something new. They can't wait to surprise their friend, the mailman, with new shoes. But the salesman measures their feet and finds the twins don't need new shoes after all. How can they surprise the mailman now?
Janet’s Thingamajigs: Janet loves how her mother calls stuff "thingamajigs" when she can't remember the word for them. Janet wants thingamajigs of her own, so she starts collecting small items she sees every day.
Jimmy wants to play with Janet's thingamajigs, so Janet wraps them up in brown paper bags and keeps them on her bed to prevent him from messing with them. The bags rustle every time Janet moves on her bed, and her mother says she sounds like a mouse in a wastepaper basket.
This short story was funny to me because my kid also likes to collect anything and everything. I think it's a perfect example of how kids like what they like, and if you give them the space to get it out of their system, they'll come through it on their own and save a lot of disagreements!
