This may sound strange to many but my daughter starting having underarm odor when she was 3 years old. I took her to the pediatrician and was told that it was normal and nothing to be alarmed about. I was told to just start putting deodorant under her arms. I was surprised to here this but did what I was told. My daughter is 14 years old now, very active and battling a sever underarm odor. For a while I thought she was simply not doing a good job with her personal hygiene and would yell at her if I smelled her underarm odor. We just recently had a long talk about her personal hygiene and she told me that she does the best she can but the odor will not go away completely. She said when she gets out the shower, she can still smell the underarm odor and she also have some bumps under her arms. When she squeeze the bumps old deodorant comes out of them with a terrible smell. I literally freaked out and have been searching the Internet for some sort of help. She has an appointment with a dermatologist on Monday and I am hoping the problem can be solved. Currently, she is using vinegar until we make it to the doctor; so far this is working but it is still embarrassing. Any suggestions, thoughts or ideas are welcome.
