It depends on the fabric. Our Lunaluxe® fabric is seasonless, which means footie pajamas keep babies and toddlers comfortable in any sleep environment. Rather than trapping heat like some synthetic fabrics, our bamboo blend adjusts to body temperature so your little one stays cozy without overheating. For colder nights, you can always layer a sleep sack over footie pajamas for added warmth. As always, follow safe sleep guidelines when it comes to layering for infants.

Zipper pajamas make middle-of-the-night diaper changes so much easier. No snaps to fumble with in the dark, no crying baby waiting while you figure out which button goes where. Our Zippies feature a convenient double-zip design that opens from both the top and bottom. Made with Lunaluxe®, they're ultra-soft against delicate skin and breathable enough to keep little ones comfortable all night long.

There's no hard rule here. It really comes down to your child's comfort and your own preference. Most kids wear footie pajamas anywhere from birth through age 3. Footie pajamas are especially great for babies and young toddlers who tend to kick off socks at night. When your little one starts wanting more independence with getting dressed, begins potty training, or if they're just ready for separates, that's usually a natural signal to transition. Until then? Keep enjoying the footies.
