We recently found this fun site called "How Stuff Works".
It has all sorts of different topics and we felt the one on how to choose a crib might be useful.
"For the sake of the consumer, a lot of attention has been paid to crib safety. Any crib manufactured after February 1974 must conform to strict safety codes, which were necessitated by a large number of serious crib accidents. If you are considering an older crib, perhaps one that has been in your family, compare its features with the current safety standards"
