AWARD WINNING SOFTNESS - We are proud to have won the 2016 and 2017 Cribsie Award for the snuggliest and softest pajamas!Our cotton is combed & ringspun. In short, we get rid of cotton impurities during the spinning process. The result is the softest cotton!

We have done all we can to ensure babys skin is only in contact with the highest quality, softest cotton. PERFECT FIT - When choosing the right size for your child, we recommend using weight and length to make your decision rather than age. Safety is our top priority so we meticulously ensure our pajamas fit snugly to minimize injury and fire risk per the federal sleepwear regulations. GRIPPER BEES ON FEET - Our no-slip grippers are perfect for bouncers, walkers, and tumblers alike! The adorable bee design adds safety and cuteness!
