My daughter is 3 years old and slept in a crib/toddler bed for the first 2.5 years. I have the crib mattress in storage now and the mattress will probably be 4 to 4.5 years old by the time a new resident will need it.
Can I use this mattress for a second LO or do mattresses have expiration dates (like a car seat)? I see that most Goodwills and CraigsList won't take used baby mattresses, so that is what prompted me to ask.
