Vintage Advice for Girls Having Their Period (1951)

We follow Mary who is 13 and has started her periods. Apparently her soiled santiary pads should be wrapped in paper and burnt. Mary wears the smallest size pad 'O'. Any ideas what O stands for??

Sanitary pads can be attached to your suspender belt or attached more safely to a sanitary belt.

It is important to wash during a period, enjoy a bath, but make sure it's not cold so that you catch a chill.

Don't fear if you feel slack or lazy during your period - this is normal.

Try to keep your feet dry! You can wash your hair, but get it dry quicky. 

There is a big emphasis on not getting a cold......I wonder why?
