Oooh this is a tough one cause I have many many books that bring back positive memories. I was a hardcore Junie B. Jones fan, but those were not “picture books” so I’m not sure if that counts. There’s some classics like “The Giving Tree”, “The Very Hungry Caterpillar”, “Where the Wild Things Are”, but unfortunately most of my favorites were ones I don’t remember the name of. Honestly, I didn’t love to read when I was little. I much preferred to make up my own fictional stories.
