You need to cut the drywall out, and remove it
then treat the studs with bleach or use a mold removal spray found at most alll home improvement stores
also set a dehumidifier close buy to remove as much moisture you can

Thanks is the black mold dangerous for my kids be around, should they be out of the house?
It is dangerous, try and contain the room with plastic, or remove the drywall, as soon as possible and treat studs. I cannot comment on if you need to leave, but if they are very young they are more susceptible in my opinion. (depends on how much mold we are talking about, fixing the problem is better sooner then later. (use a mask if your trying this yourself as it will go airborne, and breathed in, best to call in a pro)
