We've also seen the companion volume to this book, {{amazonurl|isbn=1848692048|title=Peekaboo A to Z}}, which has all the same attributes and is just as much fun.
We've seen [[Orla Kiely Numbers by Orla Kiely|Orla Kiely Numbers]], another board book but Peekaboo 1 2 3 is much more fun. we also liked [[The Selfish Crocodile Counting Book by Faustin Charles and Michael Terry]]. For something a little different, try [[Snail, Where Are You? by Tomi Ungerer]].
