I really wanted to like Iggy Peck, Ada Twist, and Rosie Revere, because they promote really positive messages. But man, the verse is really clumsy and poor in some areas. Not stellar writing.
To add to your list: anything by Julia Donaldson. The Gruffalo, Super Worm, Room on the Broom, the Whale and the Snail.
Perennial favs when my kids were 3-5
It didn't bother me that much, and there are some good rhymes. But if you want someone who takes meter seriously, check out Steven M Nedeau's books.
