(A prequel/sequel to "A Cheesy Reunion". Rated Teen to be safe.) As Lil' Cheese and his parents await the birth of Maud Pie's foal, Lil' Cheese's mom and dad recall the events leading up to his birth, and all they had to endure as a result.
Pound and Pumpkin Cake agree to look after Lil' Cheese for Pinkie Pie so that she can have a much needed break. Of course, Lil Cheese is anything but cooperative. He's intent to give his new foalsitters a hard time. Will he break them?
(Semi-related to "The Sitter with the Diamond Tiara".) Lil' Cheese is worried about having a new teacher, despite the reassurances of his parents. Luckily, his new teacher knows just how to dispel such worries.
Pinkie Pie and Cheese Sandwich take Lil' Cheese with them to visit Mr. and Mrs. Cake, who have now retired. Lil' Cheese is eager to meet the ponies that were like a second family to his mother.
Lil' Cheese accompanies his mom and dad on a trip to Ponypalooza to see his grandparents. It also doubles as a chance for him to see two of his most favorite aunts: Limestone and Marble.
When both Pinkie Pie and Cheese Sandwich are called out of town for separate but important occasions, they rush to find a suitable foalsitter for Lil' Cheese. An unlikely pony volunteers for the job, Diamond Tiara.
To Gabbro, there was nothing good about being a unicorn. It was an ever present wedge between him and his earth pony family. What good could come from using it?
