Towards the end of Bears on the Stairs, the parents give up and take the child up to bed themselves. The child thinks 'Aha - now they'll see for themselves!' but, infuriatingly, when Mum and Dad appear, the bears all hide!
I felt it important that we see them hiding, as the reader will get a kick out of the 'he's behind you' factor. I also thought that, while the parents are oblivious, the little boy should be suspicious, well on the way to spotting the bears:
Again, the first time I drew it, it was in danger of being sinister, so I made Big Bear giggly. Hopefully that has taken the sting out. What do you think?
