A mother says it?s a miracle her two children survived a ceiling collapse in their Morrisania apartment.

Brenda Medina says 9-year-old Damarilee and 7-year-old Brenden Alvarado were asleep Tuesday night when their ceiling caved. Medina says her children were under plaster, but were unharmed and did not wake up until she started shaking them.

Medina says the cave-in could have been avoided if her landlord had kept his promise to fix cracks a month ago. HHH Realty did not return calls for comment.
