When Should You Replace a Crib Mattress
For crib mattress, the useful reminder is usually the manufacturer replacement guidance, the date on the product, or the point where wear and hygiene mean it is time to replace it. Track the exact item in use, not just when you bought something similar. Replacement timing is often driven by product condition, hygiene, or manufacturer instructions rather than a universal government schedule.
Baby gear is easiest to manage when the reminder is tied to the actual replacement point, not just a rough memory of when you bought it.
