So i had baby out for some play today and was looking her over. I found 2 tiny little black bugs may'be an inch or so from her head. They just brushed off but I got one trapped under a shot glass till I can get a pic of it. I looked her over really carefully and didn't find any more. So it was about the size of a pin head and black. What is it? Is is trouble? Did it come from the substrate? I'm really really thinking I'm going to switch to newspaper to be safe.
