This may be a silly question, but something I've been wondering. I've always read to avoid hot baths/hot showers/hot tubs/anything that raises internal body temp because then you could harm baby. Well, I sleep with a pillow between my knees, usually in fetal position, so the pillow is up by my stomach. I also sleep under a comforter and it can get a little warm. My question is, is this the same thing as sitting in a hot bath or a hot tub? Could this hurt baby by raising body temperature?
