I got Littl'Uns paddling pool out yesterday as it is so blooming hot. Last year it never really got hot enough to use it (and I was pregnant so refusing to do silly things like spending ages sorting a paddling pool out!) so it was like he'd never been in one before. He was loving it, getting in and out, running round the lawn, getting back in again. Then...
"What?" (in panic stricken voice clearly thinking he had broken his arm or something from the racket)
"There's GREEN STUFF in here!!! AAAGGGGHHHHH!!!!"
"That will be grass"
