Silly Santa. He forgot to gift you those nine-millimeter pearls you’ve been lusting after.

Never mind, they wouldn’t work with the whole teething-and-spit-up routine you’ve got going on.

Indulge instead in a strand or two of Chewbeads. Made of FDA-approved silicon that won’t break in baby’s mouth, Chewbeads are the perfect accessories for moms with teethers on their hands (and hips).

The brightly colored necklaces and bracelets (think J.Crew meets Sesame Street) are easy on young gums and teeth, can be tossed in the dishwasher, and may even improve baby’s focus while nursing. Stock up on an array of colors (cobalt, yellow, ivory, wine) to match every outfit and mood.

As for Santa, he can bite it.

Available at Doodle Doo’s, 11 Christopher Street, between Greenwich Avenue and Waverly Place (212-627-3667 or doodledoos.com); online at chewbeads.com, $10.50-$29.50.
