I don’t know the title, but this is my memory of it. I grew up as a kid in the 1990s, so it would be from around then or earlier. I think it was probably made in the 1980s or 1990s, but I could be wrong. My memory of the artwork is watercolors.

Synopsis: Girl goes out for a walk in the forest. I think she brings sandwiches with her (possibly peanut butter)? She might also have had a thermos to drink something. She goes and picks berries and puts them in a glass jar she has with her. I think she ends up eating all the berries and instead fills the jar with tadpoles. Not sure if I am remembering the tadpole part correctly. It could be that she sees tadpoles in the brook in the forest. My memory is that nothing extraordinary (no adventure) happens. It’s just the girl with her thoughts and discovering interesting things in the woods. My memory of the illustrations is lush and detailed and more sophisticated.

Sorry to be so vague, but this is as good as I got! Thanks so much for your help!
