I have a developing thesis that dogs and toddlers are basically the same in terms of their demands - they require feeding, exercising twice a day (regardless of the weather outside) and rules (which they will challenge at every opportunity). I think Yasmeen Ismail recognises this too with her wonderful toddler stand-in, the dog Fred.
Fred, gorgeously rendered in loose watercolour, tries every trick in the book to avoid bedtime, before falling exhausted into his own basket on the last page. The limited and repetitive text ('Fred? - Fred?- ') allows for a lot of improvisation with tone of voice, and children can follow the action on the page without any other explanation.
This is by far my 22 month old son's favourite bedtime story. The pictures are bright and endearing which no doubt appeal, but I have a sneaking suspicion it's because it sounds like an average 5 minutes in our house (just replace 'Fred' with 'Arthur') and he finds it comforting!
