Sleeper Sac a Snuggie for the kids

You’re curled on the couch under a heated blanket for a Sunday afternoon veg-fest, and your mini-me is snuggled up next to you. What is she bundled in?

• THE TRENDLET.

A Sleeper Sac, of course. One part sleeping bag, one part luxe blanket, these perfect-for-cuddling nighttime-into-daytime items — with pillows and matching pajama bottoms — will keep your cuddle buddy cute and warm. Think high-fashion kiddie Snuggie.

• WHERE DOES IT COME FROM?

The latest in sleepover fashion is courtesy of Stacy O’Leary, founder of 10-year-old Penelope Wilberry, a Las Vegas tween-fashion company.

Two years ago, O’Leary began fashioning youngsters’ hoodies and blankets from mink microfleece. O’Leary’s husband, Ziggy, drew on them the graffiti-style images of emojis, candy, peace signs, tubes of lipstick and skulls.

In March, inspired by tweens’ love of sleepovers, she designed a 30-by-60-inch bag. Today, the sacks are sold in 300 specialty stores throughout the country.

• WHO IS SLEEPING IN IT?

Francesca Capaldi, who starred in the Disney Channel sitcom “Dog with a Blog.” Tweens at summer camp. Even moms who find it comforting to hang in sacks covered with to-go Frappuccinos and lattes.

• SHOULD YOU (OR YOUR KIDS) SLEEP IN ONE?

Cozy and soft, they are good for your kids’ sleepovers or sleep-ins. And if you are the grown-up who has a little one still nestled inside her, go for it.
