Kids picture book (large size at least 8×10″) for little girls, about a group of girls, about 4-8 of them, and they are very short and stumpy (e.g. thick legs) with big heads. They are sweet and passive. They do girly things, including ballet. Or maybe ballet through the whole book. At one part of the book they might get sleepy and take a nap under a tree. At one part there might be a group of boys who antagonize them. I read it during my childhood approx 1984-1992, so it can’t be newer than that and it is likely not much older.
Another way to describe the girls: they look human but they have doll-like proportions. Maybe they are dolls?
Update:
“The Little Girls’ Dance Class” by J. Carruth (1984).
I was able to find it through https://www.worldcat.org/ using the search criteria (year 1975-1993, juvenile, fiction, book). At first I tried searching all the “Ballerinas”, no luck. “Ballet”, no luck. I was going to do “dance” next (a lot of searches) but something all of a sudden told me to try “dance class” was something in the title so I searched that and found it! Wow, I was almost in tears when I saw the photo of the cover. I bought myself a copy online. I submitted the request on this site over 7.25 years ago, and thought of it many times since then. I never actually came back to check the site to see if there were any replies until today, and I was really disappointed there weren’t any, so that’s why I searched again on my own. The other reason I keep being reminded of this book over the years… so there’s this interesting physical/emotional feeling I get, maybe a couple times a year, it feels like my legs are stumpy/stubby like the girls’ legs in the book. Like I feel like the girls in book.
