OK, we are borrowing a bassinet from some friends for the first 3 months of our LO's life. At first, I planned to use the mattress that they used (which seems to have come with the bassinet - it's made by the same manufacturer, which doesn't sell bassinet mattresses a la carte). Then I read that it's best to switch out mattresses for each child just in case moisture and therefore bacteria could have gotten into the mattress during the first child's use (posing some risk for SIDS). So DH and I are in the market for a new bassinet mattress for a borrowed bassinet.
I ordered a new bassinet mattress, and it came yesterday. It's a bit narrow for the space - it claims to be 14" across, but it looks to me to be more like 13", and the space really needs a 15" mattress to be snug. I haven't read anything anywhere about the safety recommendations for bassinet mattresses, but regarding crib mattress safety, one baby book I read said it's OK with gaps as long as you can only fit 2 fingers in between the wall and the mattress. Another book said 2 fingers' width is too much. So now we're trying to figure out whether it's safer to use a new mattress that isn't quite wide enough for the space or the old mattress, which obviously fits the space perfectly.
We're also still searching for a different new mattress that will fit the space properly, but I was wondering what you all thought. The bassinet mattress industry seems pretty small, so finding what we need may not be easy. So far, the only one I've found that would fit is from a company we've never heard of on Amazon. DH is hoping we can find one that would fit from a more reputable source.
About the old mattress: the baby who used it before was in the NICU for the first three months of her life, so I don't even think she slept in the bassinet much, if at all. Also, the old mattress appears to have an outer shell of sealed vinyl or something, so I'm skeptical that anything actually could have permeated it. Of course, if something happens, I'll never forgive myself - hence the hand-wringing over the whole thing.
Finally, I wonder whether there's something we can do with the old mattress (like use a mattress pad/cover or something?) or with the new, too-narrow mattress (wrap it in blankets to make it thicker?) to make it less risky. Thoughts/ideas?
