Bit overrated. Didn't find the rhymes interesting for a baby/toddler, although if sung, might be lulling. The black and white pages interspersed with the coloured ones might be to give an impression of lights dimming, but my nephew only found it puzzling and flipped over faster over the grey pages, looking for the colour. I didn't find a way to make the alteration interesting, the author might have added rhyme to that effect
