Need help finding book series like Ivy and Bean ASAP

[Simon]

We use a lot of audiobooks here and my 7 yo had recently enjoyed:
The Secret Garden
Mrs. Frisby and the Rats of NIMH
The Clementine Series (author Sara Pennypacker)
The World According to Humphy (also a series)
Little House in the Big Woods (on the Prairie)
Mercy Watson (3 books)
One Hundred and One Dalmatians (the original, not Disney)

He's been reading books from series like Puppy Place, Animal Ark, Pony Friends, etc. Maybe the Penderwicks or Piper Reed Navy Brat. Pipi Longsocking, Rebecca of Sunnybrook Farm, or Heidi.

DGD1 loved those! The only drawback is, as you said, that there are only two so far. Hope there are more in the works!

My daughter is gobbling up books right now, and the librarian had a lot of good suggestions after she read Ivy and Bean. She loved the Just Grace book she read, and we will definitely read more. She loved Ruby Lu which is also a series, and Geronimo Stilton. We are reading Chickadee right now by Louise Erdrich. It's a little tougher, but great and full of nature adventures. What about the Phantom Tollbooth? I saw that at the library and would have picked it up except we had too many out already. DD also loved Clementine and Judy Moody which have been mentioned

And you might not want to get her started, but Harry Potter is amazing. My son started it the spring of 1st grade and had finished them by the time he started 2nd. He just read constantly. Now he's ready them through 3 times! I know my daughter will love them too, I just need to start it for her...

Also, The Name of this Book is a Secret is a great book.
