Abstract: A heat blocking apron assembly includes an apron that may be worn on a front of a pregnant woman's body. A first strap is coupled to the apron and the first strap is placed around a neck of the pregnant woman. A pair of second straps is provided and each of the second straps is coupled to the apron. Thus, each of the second straps is selectively tied around a torso of the pregnant woman. A shield is coupled to the apron. The shield is comprised of a thermally insulating material. Thus, the shield inhibits heat from a heat source from being transferred to an unborn baby.
