Don't know the title, non-fiction book I'd love to buy for DDs.
Aimed at pre-schoolers, about understanding passage of time. Each page was illustrated double page spread about something that take a long time and an associated incident that takes a short time.
Example pages were definitely:
It takes a long time to build a tower of blocks, but a short time to knock it down (illustrated with dog and children knocking tower down).
It takes a long time to make a jelly, but a short time to eat it.
I think it was A4 size or similar. Am child of 80s-90s. expect it was conteporary at the time.
Hit me up, bookworms! Thanks!
