Ok, I have to admit, as soon as I heard this book was coming out I knew it would be perfect for my eldest son, who is three. He's vehicle-mad and loves a good bedtime story. I wasn't expecting it also to be a hit with my 18mth old because he's not quite old enough to sit still for most paper books (still loving the board books. And occassionally chewing them!). So for us this book is perfect for just before bed with the two boys snuggled under each arm. The oldest is old enough to shout 'Goodnight Digger!' at the appropriate places whilst the littlest just shouts 'Gigger!' at random. A lovely way to wind them down at night time.
