Could Schrodinger's Cat Die of Toxic Mold?

Along the lines of "what you don't know won't hurt you," we have so far failed to get a mold evaluation in the toddler's room, despite knowing that the studs are rotted and not attached to the foundation, the roof and rafters are rotted, and the whole room held together pretty much by the drywall and paint.

Why?

Because it wasn't our house, it was my father-in-law's, and we were just squatting there til Bad Cohen finished grad school. Which is taking a lot longer than planned, since he became seriously affected by fibromyalgia and various other nasty chronic stuff in the last 3 years.

But now the toddler's showing signs of being overtired, having environmental allergies, and possibly developmental/sensory integration issues that are affecting his ability to deal with preschool.

Yay.

Unfortunately, we can't fix anything with his room without dealing with the falling-down ridiculousness that is the house (of which BC now owns 1/3, with his siblings owning the other 2/3).

With all the other traumas and chaos going on in our lives, not to mention being broke, I just can't deal with moving this summer, especially if we're moving to another city/state next year so BC can pursue a PhD.

Am I a bad mother if I just resolve to go in and clean his room more often, and hope that summer's dry spell clears things up?

Ugh. Ugh ugh ugh.
