Jenny's baby brother Henry is having his one-month birthday -- his first-moon, as it's called in Chinese. And even though Jenny's sure he doesn't deserve it -- all Henry does is sleep, eat, and cry -- there's a big celebration planned for him. Together, Jenny and her grandma get everything ready, from dyeing eggs a lucky red to preparing pigs' feet and ginger soup. And someday, when Henry's old enough to appreciate all her hard work, Jenny will tell him how lucky he was to have her in charge. The childlike charm of Lenore Look's story is perfectly captured in Yumi Heo's naïve illustrations, which give readers the impression that Jenny drew them herself.
