My Baby has BO?

Anna
My baby has severe body odor. I talked to the pediatrician about it, and she said that as long as there is no abnormal hair or menses-like blood, it's probably nothing to worry about, but also that it's not super normal. She stays very clean, she's not too warm, and I'm trying to keep powder under her arms to make sure it's dry. I wouldn't worry about it if it was occasional, but it's often, and it's very intense. I know she's too little for deodorant, but is anyone else having this problem, and what are you doing to help?
