I'm due no2 in a few weeks, and will be reusing the next2me crib from no1. Do I need a new mattress?
I know the recommendation is to buy new if the mattress was used by a baby from another household, but can't really find clear guidance for reusing on two related babies. DD is 3 1/2, so the mattress hasn't been used for 3 years if that makes a difference - and the cover does seem to have gathered quite a lot of dust (though I'll obviously wash it).
