This theory is that a certain fungus eats chemicals in bedding and puts off a toxic fume over time- so the longer the mattress is exposed to baby spit up, pee etc, it gets worse. It sounds completely psychotic and not possible but a lot of people took it seriously, I guess. I've read enough to not be very freaked out about it but I'm still pretty anxious about SIDS and probably will be till he's one.
I'm considering talking about the possibility of PPD in the form of anxiety at my post partum appt this week. I'm pretty distraught about this. Possibly more than the normal level parents usually are.
We actually went out and bought a crib tonight and are attempting to side car it to the bed now. Well, my husband is.
