i think you can use a mattress for a child until it wears out. gets saggy. or gets peed on too many times. then you can get a new one. if the mattress looks good. feels good. and smells okay just change the sheets and mattress pad and use it.
can i use the same mattress for more than one child? . i've heard that you should use a new mattress for each new child in a family i've also heard that that is a ruse to sell more mattresses. which is true? i've used the same mattress for 3 children but now with grandchildren i wonder if i can use one mattress (not the one used for my children) more more than one grandchild.
