How old are your children, and how often are their ablutions?
How does that compare with your age and your childhood?
I was born 1980 and were washed in the sink or in front of the living room gas fire til I was about four.
After that it was bath night on a Sunday, both sisters in the same tub. I also remember being sent to wash my hands or wash behind my ears(??) with a flannel before bed.
I don’t think I really had a shower until I was a teenager and staying over at my boyfriend’s house or swimming regularly.
I don’t have children, but my natural nieces/nephews bath once a week (shared bath) and those of my boyfriend shower fail (separate en suites).
