Do you think at the tween stage they should shower more often? Do you have a hard time getting them to shower? When my son turned about 12 i noticed he and his room had a "smell" that was suddenly different. I think he noticed it too and was on a cologne kick. He is in college now. I didn't notice it with his older sis but my youngest daughter is 9. I notice her clothes smell funny. When i do laundry everything that comes out of her hamper reeks. It's not a sweaty smell like dh's clothes. It just an unfamiliar odor i didn't notice before. And her bff downright stinks. It's a sickly sweet/sour smell. I had to give our neighbors kids a ride to school the last few weeks since one of their cars was in the shop. I had all these kids between 9 and 14 in my car and it was awful. Funk is all i can say. I mentioned it to their mom and she said they all shower and wear deodorant but she noticed it too, especially feet and bed sheets.
