The maker of an infant bathtub will recall 86,000 of its products after receiving reports that 11 children were injured when the sling holding them in place unexpectedly detached.

Summer Infant announced the recall of 86,000 Lil’ Luxuries Whirlpool, Bubbling Spa & Shower with fabric slings after determining the slings are missing a clip that connects to the headrest to hold a child in place.

The infant bath tub is a battery-operated whirlpool bath with motorized jets intended for use with children from birth to two years

According to a recall notice posted with the Consumer Product Safety Commission, the missing clip can cause the sling to slip down the tub’s side, posing an injury and drawing risk to babies.

So far, Summer Infant says that it has received reports of 91 incidents in which the sling detaches, including 11 reports of infants receiving a bump on the head.

The recalled products were sold between Oct. 2012 and Oct. 2013 at retailers such as Toys “R” Us, Babies “R” Us, Amazon, and others. The tubs can be identified by the item numbers 18840, 18850, 18863, and 18873.

The company warns customers who own the affected products to immediately stop using the fabric sling and contact Summer Infant for a replacement sling equipped with the needed plastic attachment clip.
