I was bathing my LO every day, but she started to get dry skin on her elbows, so I lessened it to every other day or sometimes even every two days. But I was using soap every time, so maybe that's why. I think the water could possibly have something to do with it too, because the warmer the water is, the more moisture robbing ability it has, I don't know if that's because of sweating. But then the temperature a baby needs for safety is probably not warm enough to cause any dehydration. I'm rambling! Anyways, you should be fine doing it every day, but that depends on the baby, the temperature, the soap, etc. You could start doing it every day with soap if you want, then eliminate the soap if it causes problems. I just don't bathe her every day anymore, but I freshen her up on her face & butt, and in all the creases and fat rolls, with a baby wipe. Good luck with your endeavors!
