 [ Symptoms ] can i use the same mattress for more than one child  i have heard that you should use a new mattress for each new child in a family i have also heard that that is a ruse to sell more mattresses which is true i have 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 [ Disease ] 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
