Mold/mildew

Last night I noticed mold/ mildew growing on the bathroom ceiling in our apartment and I have contacted the maintenance but haven't heard anything back yet. I am super stressed that my daughter was exposed to it and it's my only bathroom with a tub so I didn't even give her a bath tonight cause I don't want to take her in there at all. She seems fine and isn't showing any signs of health issues but should I take her to the doctor anyways to have her checked? Has anyone else dealt with this before? Any advice is so appreciated.
