I've titled this entry "Read-Alouds for Boys" because below you'll find books our boys enjoyed when they were preschoolers and a little bit older. However, as many of you commented yesterday, many boys enjoy "girl" books and many girls enjoy "boy" books. I often find a boy listening in the hallway while I'm reading Milly Molly Mandy to the girls, although they'd probably never admit it.
Children of the New Forest (all-time favorite here)
Swallows and Amazons (another favorite)
Men of Iron (favorite, too)
