It looks like Leo had his first dream (that we are aware of). He woke up after a nap today and immediately told Papa that he'd been running after the Were-Rabbit, he was very emphatic about it; "runnin' after the wea-wabbit, runnin' fast!". He'd seen Wallace and Gromit the night before. So that means both kids' first dreams were of cartoon characters; I'm pretty sure Clara's was of Winnie-the-Pooh.
