Once your baby is all grown up, the Modern BabyLetto Newhaven Crib Full Size Rail Kit will turn her Newhaven Crib into a big girl bed. Because the conversion rails have hidden hardware, there aren't any visible screw holes to tempt your little one's curiosity. This kit also comes with full-sized canopy rails as another bedding option. These rails are made from pine wood and have a non-toxic finish.
