Health Canada suggests since playpens do not meet the same safety requirements and are not as durable as cribs, they are not designed to be used as a sleep surface. They recommend....
- Do not leave an infant sleeping in a playpen for extended periods of time.
- If a change table or bassinet is provided as an attachment for the playpen, never place a baby in the playpen while the change table or bassinet attachment is still in place.
- Do not add blankets, pillows or an extra mattress to a playpen. The use of these items could lead to suffocation.
- Check that the mattress pad is firm. Mattress pads that are too soft or worn down in any area could create a suffocation hazard.
