Stressful but funny in hindsight

I have a stressful story from the other day. I popped to the supermarket
on my way home from a coffee get-together. Bevan started crying in the
trolley bucket seat and I picked him up to quieten him. I realised that
he had wet through his nappy at the front. He was just wearing a
treasures giggles rather than a cloth one like we've been starting to
use regularly.
So his jeans were all wet on the front and I had to hold him so that
no-one could see his wet patch and he got heavy really quick.

Then two different nice staff at the checkout offered to hold him while
I unloaded the trolley and paid and so I was like - "no, it's fine!" so
that they didn't get wet from him.

Argh - what a stress moment!!! They must have thought I was really
overprotective and ungrateful too...
