BabyLegs® became a leader in children's fashion when it created a new niche for its original line of children's leg and arm warmers in 2005. Invented by a mom to keep her daughter's legs warm while she was diaper-free, BabyLegs® leg warmers quickly became a parenting essential because of their utility, practicality, and stylish appeal. We've since added socks and tights, and more is on the way! BabyLegs® The Original. Like You.
