Absolutely adorable addition to your little one’s crib! This includes the wooden arm to attach the mobile to your crib. The screw or fitting inside of the area to tighten to crib is stripped, so it will need replaced. Our little one was out growing the mobile, so we never replaced. This does not play music, but there are bells attached for stimulation. One bell fell off, so I had replaced with a painted bead to match. Please check out my closet for similar items. Bundle to save! Smoke and animal free home.
