A picture book about the Chinese cultural tradition of commemorating a baby’s “100th Day” and celebrating sibling love.

Anya loves having special days with her mom and dad–rainy days, yellow days, stay-in-the-park for hour days.

Then her younger sister is born and Anya finds herself feeling overlooked and forgotten. Why does Hana have to get all the attention? Her family is busy preparing for her younger sister’s 100 Day celebration, a Chinese tradition that commemorates an infant’s 100th day with good luck rituals and customs like the delectable ang ku kueh cakes, red envelopes, and baby’s first haircut.

As the day approaches, Anya learns to appreciate her baby sister, learning that sometimes love comes slowly, in days and moments that creep up on you, and hold onto you tightly–as tightly as a little sister can.
