At SUNNY & KO, we prioritize your child’s safety and comfort in every detail, including our carefully crafted sizing. Our pajamas are designed to be snug-fitting, in accordance with the CPSC's safety standards, which help protect children by reducing flammability without the need for harmful chemicals or flame retardants. In addition, we’ve added extra length to our pajamas, allowing them to grow with your child for a longer, more comfortable fit. Available in sizes ranging from newborn to 7/8, our pajamas provide a cozy, safe fit for babies and kids as they grow.
