If you do use a blanket, place baby with feet to foot of the crib.
Tuck a thin blanket around the crib mattress, covering baby only as high as his/her chest.
Use only a fitted bottom sheet specifically made for crib
use.
No missing, loose, broken or improperly installed screws, brackets
or other hardware on the crib or mattress support.
No more than 2 3/8 inches (about the width of a soda can) between
crib slats so a baby's body cannot fit through the slats; no missing or cracked slats.
No corner posts over 1/16th inch high so a baby's clothing cannot
catch.
No cutouts in the headboard or foot board so a baby's head cannot
get trapped.
For mesh-sided cribs or playpens, look for:
Mesh less than 1/4 inch in size, smaller than the tiny buttons on a
baby's clothing.
Mesh with no tears, holes or loose threads that could entangle a
baby.
Mesh securely attached to top rail and floor plate.
Top rail cover with no tears or holes.
If staples are used, they are not missing, loose or
exposed.
