For some reason, Penguin decided to keep a lot of this series in print, but not this first book. Prequel to books that remain in print - pictures by Arnold Lobel - why not keep publishing this? I don't know. I e-mailed the author and she didn't seem to know either.
Both of my kids, who are five and almost two, have loved these books. I think they relate to the quiet domesticity of them and Oliver and Amanda's sibling relationship. As a parent, I particularly appreciate the part in this one where Mother patiently gets Oliver and Amanda into their snow clothes, leaves them alone for a minute, and comes back to find that they've taken everything off. She starts crying. "Mothers don't cry," says Oliver, concerned, only to hear his mother reply, "Well, I am." Oliver and Amanda are based on Jean Van Leeuwen's children, and you can really tell she's been a parent of little kids. No unrealistic supermoms here.
The almost-two-year-old loves when Oliver makes pretend food for his grandmother, and when Father pretends he doesn't know it's Oliver under the covers. ("It must be a meatball.") I think she's had me read this about ten times over the last three days. Do yourself a favor and track this one down if you liked the more easily findable parts of the series.
