...loo?
I took dd1 to a b'day party - there was another little girl there whose mum had left her (which is fair enough, I would go if dd let me [sigh]). The girls are all around five.
When this girl needed the toilet she asked me to go with her (this was at a community centre) - no problem, but then she had to do a, ahem, poo, and I ended up cleaning her up as well. Felt very strange to do it for a child which was not mine!
Was also v. intrigued at the differences in cleaning techniques that seem to exist.
