WAYNE, NJ (WCMH) – Toys R Us has recalled around 53,000 pacifier clips because of a choking hazard.

The children’s retailer says that the spring mechanism in their line of Babies ‘R’ Us pacifier clips can break and release small parts, presenting a choking hazard. The recall involves clips that were sold in an assortment of six colors and character designs between February 2015 and April 2016.
