Your baby usually will be unattended when in his crib, so this should be a totally safe environment.
Falls are the most common injury associated with cribs, even though they are the easiest to prevent.
Children are most likely to fall out of the crib when the mattress is raised too high for their height, or when the side rail is left down. If you use a new crib or one manufactured since 1985, it will meet current safety standards. There should be no cutouts in the headboard or footboard, as your child's head could become trapped in them. Loose clothing can become snagged on these and choke your baby. As a precaution, strip the old paint and then repaint the crib using high quality, new enamel.
