Our school had a small locker of toiletries. Many times a teacher had to pull a child aside and privately give them a little bag of soap and shampoo. I remember that one boy I had to do that with. I'm not exaggerating when I say that his body odor literally made eyes water. He told me that his mother was ill (doing chemo, as I found out later) and couldn't get out of bed, so he was making do best he could. We got him to bring his clothes into school, and we washed them in the athletic washing machines.
There was a little girl whose mother would sell everything she could get her hands on to support various habits, including her daughter's clothes. So, one of the female teachers set up a little closet for her at school. She would wear her rags into school early, and then get changed into the nicer school clothes. At the end of the day, she'd switch back. She didn't dare wear the nice clothes home for fear her mother would sell them.
Anyone who has ever worked in a school has similar stories.
