Yes Mommy it is safe and recommended. Since it is really hot that the heat can do more damage (e.g. rashes) than multiple baths. We just have to use soap with moisturizers if you are concern with the possibility of drying the baby's skin. But what I can recommend though, is tea bath. I put.1-2 bags of tea on baby's hot water and use that for her soak. And also add it to her water for rinsing. :)
