+1 for Room on the Broom, don’t foget Charlie Cook.
While Julia is great, two books that also have been a favorite, and now reading to my youngest are:
One more Sheep, Mij Kelly & Russell Ayto, about a farmer who keeps falling asleep before he counts his 10 sheep.
Man on the Moon, Simon Bartram, about a guy who’s day job is going to the moon and entertaining passing spaceships and is in denial about aliens. This also has beautifully detailed drawings.
Many happy memories reading these two.
