The size of the neck opening is too large for infants 0 to 6 months, which can allow an infant's head to slip into and be covered by the sleep bag, posing a risk of suffocation.
The bottom locking mechanism can fail to lock properly if a spring is not installed, allowing the bassinet to tip to one side and cause infants to roll to the side of the bassinet. This poses a suffocation hazard to infants.
