Over the course of a day, big brother Albert manages his interactions with his little brother Baxter and the feelings that result, in this relatable romp through the alphabet.

Big brother Albert gets increasingly frustrated with little brother Baxter. Crying! Diaper! Hungry! Irritated! A normal day and a familiar sibling interaction escalate alphabetically until Grandma resolves all the problems, with an X for a kiss goodnight, followed by Yawn, and, of course, ZZZZ.
