I agree its hot baths that can cause harm not so much showers..i researched this myself because i LOVE LOVE LOVE hot showers and honestly its the only thingvthat aliviates my back pain..
Just make sure your skin doesnt go red raw because of the heat hun :)
Baths, rather than showers, are of concern. Baths, like hot tubs, submerge the body in a constant source of heat while showers are intermittent in that not all of the surface area of your skin is covered at one time.
I wouldn't think it would hurt the baby if it didn't hurt you but I've never heard of this concern. Can your water really hurt your baby?
Just don't toast yourself. Don't worry, that should be least of your worry.:)
