I Am Too Absolutely Small For School

The critically acclaimed Charlie and Lola books- — now an animated series on television!
Lola is not so sure about school. After all, why would she need to count higher than ten when she never eats more that ten cookies at a time? Once again, it’s up to ever-patient big brother Charlie to persuade Lola that school is worthwhile — and that her invisible friend, Soren Lorensen, will be welcome, too.
“The children’s relationship is refreshingly noncombative, with Charlie as the protective and affectionate older brother who is appreciative of, rather than annoyed by, his sister’s quirkiness.” – SCHOOL LIBRARY JOURNAL (starred review)
