Kolcraft Enterprises has recalled over 1 million units of their play yard. The company says that the side rail on their play yards may fail to latch, causing your child to fall if they push on it. At least one child has suffered a concussion. If you have such a unit please stop using it immediately and contact the company to determine whether the unit can be repaired or should be discarded. Parents please be especially mindful of any toys, games, or play areas where the risk of falling exists. Falls are the leading cause of serious brain injuries in children under the age of 10.
