While buying lightly used items from a thrift store or online is a smart way to save money and reduce waste, there are some things you should never buy used. Avoid used cribs, especially those made before June 2011. Safety standards changed significantly after June 2011, including new regulations on things like the height of the crib, the slat width and even how the mattress fits. These standards were changed to make cribs safer for the baby. When in doubt, don't buy it. And don't donate a crib if you know it predates those changes.
