If you didn’t write it down, it’s possible you’d forget your own name.

Chances are you’ll always remember the day your child was born (hello, eighteen hours of labor), but why risk it? Set it in stone with a baby birth plaque by Rae Dunn.

The local ceramicist will imprint your new bundle’s name, birth date, and weight in Dunn’s signature old-fashioned typewriter lettering on white clay. Choose an icon (party hat, crown, ladybug) to reflect Junior’s budding personality.

Think of it like a 3-D birth certificate. Or one that’s a lot harder to misplace.

Available at Egg and the Urban Mercantile, 85 Carl Street, between Cole and Clayton Streets (415-564-2248); online at etsy.com. For more information, go to raedunn.com.
