Some parents or friends pass on their used baby items. This is a friendly poll to see if any one has purchased a used crib. Re-certifying a used crib for safety may be a good idea. A new mattress can be fitted in a used frame removing the chance of soiled stains in the old mattress. Wipe down and disinfect the frame before using. Even a new crib should be cleaned especially if it was on a showroom floor. New babies are acceptable to catching a cold or virus until their immune system builds up.
