Bath night once a week, and the only day in the week in winter when there was heating in the bathroom!
When we were small, we were told to hold a folded wet face flannel infront of our eyes while our hair was washed. This was supposed to prevent shampoo getting into our eyes, but it did not work and the shampoo stung.
We had ducks and boats in the bath - great fun.
I remember at the age of three (I think) being told off for sucking soapy water out of my face flannel, and on a different occasion for weeing in the bath and saying it tickled so nicely.
You should have seen Mummy's disapproving and embarrassed expression. This was long before children, especially I suspect, little girls were allowed to "play with themselves."
If it was very cold in the winter, we were bathed in the big deep sink meant for washing clothes in, or had our hair washed at the kitchen sink.
The only time I remember having my bottom smacked was when I, aged four, refused to have my hair washed. It was washed and I cried so hard that Mummy never smacked me again. She did not realise, and I never told her, even after I was grown up, that I cried, not because it hurt, but because I was simply furious with her.
