How could black mold grow on a pillow in a week??

I change DD1's sheets every Saturday.  Last Saturday there was nothing on the pillow.  Yesterday there were black spots all around where her head would lay and a little bit on the other side.

I asked my dad and my neighbor had mold in their house both said its mold.  I just don't know how it got there.

She's still in a crib, hasn't peed, hasn't drank water in there.

She has asthma so I'm worried a bit.  I at first thought it was a stain of some sort and smelled the pillow and its odd that this morning I work up with a stuffy nose.  Maybe just a coincidence?

I know it sounds freaky and I'm at a loss for an explanation.  The pillow is currently on the porch.  I'm just wondering if I should have anything checked or let it go and keep an eye on the pillow daily.  I keep her room super clean with the asthma as with the house and the house is so dry. 

I'm at a loss.

Mold is everywhere and in every home.  It is most likely from drool and somehow got covered in such a way that it couldn't dry out.  I would wash it in the washing machine with a touch of clorox, then maybe again with some vinegar because I hate the smell of clorox.

That's some serious drool, lol.

It ranks up there when my DH leaves towels in the washing machine for a day or two.  Then I go to do laundry and it reeks.

Did she go to bed with her hair a little damp?

 I know!  No, I dry her hair.  I did have the mist humidifier on for 2 days when her cough was acting up, I don't know if that didn't help.  But I don't know if it would just cause it to be where her head sleeps.

Its not a big spot but small dots just in the head area.
