She's the sweetest and her wardrobe should reflect that, so dress her in this adorable toddler girl's 3-piece pajama set from Btween. Made from soft stretch fabric, it includes a graphic crew neck short-sleeve t-shirt, a printed pair of pull-on shorts, and a matching hair tie. Fabric and fit are important safety considerations for children’s sleepwear. Sleepwear should be flame resistant or snug-fitting to meet U.S. Consumer Product Safety Commission sleepwear requirements.
