L.P.
It could be something that she is eating or drinking. My daughter had a severe problem with body odor. Bless her heart, she could take a shower, put on deodorant, baby powder, perfume/body spray,etc. within 30 minutes, she would smell so bad you could not stand to be close to her. I carried her to the doctor and didn't get any answers. It was awful. Then I just so happened to find out what was causing this awful problem. I went to Wal-Mart to buy soft drinks for the weekend. My daughter loves Cherry Dr. Pepper but Wal-Mart was out of them so I got some Regular Dr. Pepper's and some A&W Cream Soda. When Monday rolled around I noticed she wasn't stinking anymore. It was the cherry flavoring causing her to have the bad odor. So she gave up drinking Cherry Dr. Pepper and her problem is solved.
