Blue Rainbows Fitted Crib Sheet product page

A properly fitted crib sheet is one of those small details that makes a real difference for safe sleep. Loose or ill-fitting sheets can bunch up or come away from the mattress corners during the night, which poses a safety risk for babies. Our Crib Sheets are fully elasticized to stay securely in place on standard and mini crib mattresses, giving you one less thing to worry about at bedtime. The AAP recommends a firm, flat sleep surface with a fitted sheet as the only bedding in the crib for at least the first 12 months, so getting the fit right matters.

Most families find that 3 to 4 crib sheets is the sweet spot. That gives you one on the mattress, one in the wash, and a backup for the inevitable middle-of-the-night changes. If your baby is prone to blowouts or spit-up, having a few extra on hand means you're never scrambling at 2am. Our Crib Sheets come with a matching reusable pouch, making them easy to store and grab quickly when you need a fresh one fast.

A good rule of thumb is once a week under normal circumstances, with an as-needed change any time there's a blowout, spit-up, or diaper leak. Babies spend a lot of hours in their cribs, so fresh sheets matter for both hygiene and comfort. Our Crib Sheets are made with Lunaluxe®, which holds up through regular washing without losing that ultra-soft feel, so rotating through a few sets stays easy and low-effort.
