About 320,000 cribs sold at Toys R Us, Babies R Us, KidsWorld and Geoffrey Stores may not be safe.

The maker, Jardine Enterprises, recalled them because wooden crib slats and spindles can break, creating a gap, which can pose an entrapment and strangulation hazard to infants.

The U.S. Consumer Product Safety Commission said that there have been 42 incidents of crib slats and spindles breaking. Four children became entrapped in the space. Two of the children had abrasions and bruising.

Many different styles and finishes are included in the recall, and a full list can be found at JardineCribRecall.com.

The cribs were sold January 2002 through May 2008 for between $150 and $300. One model, the Mahogany Positano Lifetime Crib, sold for $450.

A news release said consumers should immediately stop using the recalled cribs and contact Jardine to receive a full credit toward the purchase of a new crib.
