Change in the Round

Anyone who's tried to change a diaper on a typical rectangular changing pad knows the frustration that led Grace Welch of San Francisco to create Patemm Pad, a round changing pad from which even the squirmiest baby can't roll off. They also know frustration No. 2 of the off-site, diaper-changing experience: locating diaper and wipes while, oops, where's that wriggly baby going? By the time her second was born, Welch was determined to make her life easier. Patemm (named after Patrick, now 5, and Emma, 2 1/2 ) comes in two sizes, with or without pockets, that you can open easily with one free hand.

$30 to $48, available at Patemm.com .
