They say learning begins at home. You say: Um, duh. Here are three new no-brainers for launching the education of your baby, preschooler, or kindergartener.

Baby Virtuoso CD
What it teaches: Babies’ growing brains are sponges for musical building blocks (intervals, chords). Local musician and dad Adam Schwartz’s new CD features ten harmonic listening exercises in piano and flute, designed to forge the neural pathways of musical fluency.
Bonus: Track ten, a lush piano rendition of Brahms’s famous lullaby will soothe unsuspecting nippers to sleep.
Get it: $12 online at babyvirtuoso.com.

How to Choose the Best Preschool for Your Child
What it teaches: An exhaustive guide to the world of playdate interviews and financial aid forms, this new book will ease the anxiety of the preschool quester. Plus, it can be tapped selectively rather than cover to cover. If you’re starting late, two worksheets will get you up to speed.
Bonus: Meet local author Jenifer Wana on Friday, 5:30-6:30 p.m., at Cover to Cover Booksellers.
Get it: $10 online at amazon.com.

Kidlandia Customized Maps
What they teach: There’s nothing more thrilling for a kindergartener than sounding out a new word — except for maybe ruling her own land. These fantastical maps grant both: the website allows you to create a kingdom named for your little reader and furnish it with custom cities, ports, and creatures. Kidlandia then prints your map large or small, on canvas, paper, or vinyl wall clings.
Bonus: For kids who are over fantasy, customizable U.S. and world maps are available.
Price: $29-$149 online at kidlandia.com.
