Hellobee Boards

I'm reusing our crib mattress. It's also been covered with a waterproof mattress cover, and LO has never had an accident in there.

It's really confusing because I've heard what you said, that reusing mattresses is a no-no. But I've also heard that new mattresses are questionable because they're off-gassing more than one that's been well aired out. I *think* I'd get the new mattress for the new LO, just so the toddler could have the consistency of keeping their mattress. Not that that answers the question really, but with so much conflicting information I wouldn't be able to decide any other way.

So when you google "SIDS and mattress toxins", several websites pop up that have impressive names like "The SIDS prevention organization", but then they actually just sell mattress covers that supposedly prevent this toxic gas, and therefore prevents SIDS.

When trying to find any credible sources, I found this: http://www.firstcandle.org/cms/wp-content/uploads/2009/08/Toxic_Gas_Theory.pdf

We already know that the medical community doesn't totally know what causes SIDS, and the mattress theory doesn't explain why babies sleeping on couches or in rock-n-plays, etc would die from SIDS.

TL;DR: It's an unsubstantiated claim that mattress toxins cause SIDS.

I'm reusing the mattress as we're getting DD a big bed before the baby comes.

My older LO will be moving into a full size bed, but we are getting a new mattress for our second. My bigger concern is that they lose firmness over time which increases the risk of SIDS.

@78h2o: never! But we haven't potty trained, and she's always slept in a sleep sack (can't take her diaper off) and doesn't take liquids into the crib.

We will be reusing LO 2's mattress for the new baby.

@Anagram: same for us. We reused the crib mattress and our older LO got a new twin.

@Corduroy: At the risk of being a bit off-topic, there actually is some amazing new research on SIDS - we could potentially be so close to figuring it out! http://www.seattletimes.com/seattle-news/health/one-seattle-childrens-doctor-thinks-he-close-to-stopping-sids/
