My daughter is 12 weeks pregnant and living in a home where a kerosene heater is main source of heat. I'm concerned for her and the baby. Should I be? I took her a space heater to use in their room when sleeping and told them to keep winow up some in their room. We have heat pump and she is considering coming home until the birth because of concerns. She has been having bad headaches, but doesn't know if this could possibly be from the heater. She gets nauseaus when it is initially lit from the smell. Once the smell goes away she sas she's ok, with the headaches.being the exception. Should either of us be concerned for her or her baby?
