We received an heirloom crib that many family members used. In order to use it however, some work needed to be done to bring it up to safety standards.
First, it was originally a drop-side crib. These things are deathtraps to today’s standards. Additionally, the wall slat width was substantially larger than todays ~2″ standard. Those two things combined basically meant that new walls needed to be built from scratch. Also, my father-in-law spent some effort refurbishing and paining the crib before I took it over.
