We used a rocking crib with my little boy, and still have the mattress. It has been stored well, and I have washed it in the washing machine today to have a close look at it. All my family are saying to just air it outside a lot when it's dry and use it again, but I was wondering , would you? I know there's been loads in the news about mattresses, but I'm sure in other countries babies get on fine on old mattresses, and even in boxes and on the floor in the third world. Is it really worth me buying a brand new crib mattress? (I chucked my cot matress so will have new one in a few months anyway) Any advice please?
