We could lament the passing of independent children's bookstore Enchanted Forest, as we did in 2002, but the homogenization of American booksellers is a tired story by now. You're gonna end up going to one of a handful of chains in Dallas, and Borders is the best pick. One thing that's extremely helpful is that they organize books by reading levels--from baby on up--instead of slamming the books on the shelf by author's name (which you hardly ever know, since most children's-book buyers are browsing). There is a good selection of foreign-language picture books; LeapPad books and cartridges (buy the LeapPad itself at Wal-Mart or Target; Borders' is too expensive); sticker books; Usborne titles (high-quality educational books favored by homeschoolers); and generally helpful staff. Also, Borders has a rewards program for kid-book buyers: Buy 10 kid items, get $5 off your next children's purchase.
