A few months ago my infant daughter started screaming in the bedroom. Not a just-woke-up scream or a change-my-diaper scream but an urgent, distressed scream.

My wife had just gone back to work from maternity leave so I was obsessive about checking on the baby. A few minutes prior she was relaxing in her Fisher-Price Rock ‘N Play. But when I peered at her she was face-down wailing in the inclined sleeper.

I grabbed the baby; called my wife stammering with panicked guilt; and tossed the product into the bowels of the basement. The Rock 'N Play was recalled April 12 due to infant deaths.

Here’s what you need to know about the recall and how to get a refund:

Which Rock ‘N Play models have been recalled?

All 4.7 million of them.

Why has the Rock ‘N Play been recalled?

More than 30 infant deaths have been reported in Rock ‘N Play sleepers since the products debuted in 2009. The fatalities occurred when the babies rolled from their back to their stomach, "or under other circumstances." The recall was made April 12, 2019, after Consumer Reports and the American Academy of Pediatrics urged for the recall.

Positional asphyxia is when a person can’t get enough air to breathe due to the positioning of his or her body. It is a common cause of death in infants and usually happens when their mouth or nose is blocked. Positional asphyxia is also a potential danger in car seats when a child’s head can slump down or flop, causing the airway to be cut off and hyperflexion of the neck.

What should I do if I own a Rock ‘n Play?

Discontinue using it immediately and review the recall announcement.

How do I get a refund?

Here are the instructions to proceed with the return.

Fisher-Price asks you to mail two small hub assembly parts. The hub assemblies are essentially your proof of purchase. Package the hub assemblies and return them to Fisher-Price in a prepaid shipping label. If you still have your original receipt, include it in the mailer. If you don’t, write the month and year of purchase on one of the parts.

You can click through the recall form on the Mattel site or contact Fisher-Price at (866) 812-6518 from 9 a.m. to 6 p.m. Monday through Friday.

You can also report an incident to the U.S. Consumer Product Safety Commission with an online form.

How do I disassemble the hub assemblies?

Fisher-Price posted a PDF with instructions on how to remove the hub assemblies for each model.

Will I get a full refund?

It depends.

If you’ve had the Rock ‘N Play for less than six months you’ll get a full cash refund. The cash refund will be for the suggested retail price if you did not include a receipt. If you included a receipt you’ll be reimbursed for the full amount, including sales tax.

If you’ve owned the product for more than six months you will receive a voucher “for a new Fisher-Price product commensurate with the amount of time you have owned the Fisher-Price Rock ‘N Play Sleeper.” Fisher-Price has not yet listed the range of values for the vouchers.

How long will it take for the reimbursement?

Allow 12-16 weeks for the return to be processed.
