Lizzy is playing on the floor minding her own business when Step-Mommy Adriana and Auntie Mandie start fussing over her diaper. She's insisting that the crinkly diaper is still dry, but Step-Mommy gives her an embarrassing diaper check. When Step-Mommy leaves the room to get Lizzy a bottle, Auntie Mandie teases her relentlessly about how much of a baby she is, and that the diaper will be soaked eventually. Lizzy shakes her head but is squirming around more and more as she is being teased. Finally when Auntie Mandie goes to help Step-Mommy, Lizzy can't hold it anymore, she floods her thick diaper- and of course as soon as she stops both adults come back into the room.

Step-Mommy Adriana bends down and feels Lizzy's warm, pee filled diaper, then decides that her baby girl will be drinking her bottle during a humiliating diaper change. Lizzy begins to protest, but Auntie Mandie promises that if she behaves, they'll be a big surprise for her. Still pouting, Step-Mommy and Auntie lift up Lizzy's bare legs to give her a firm spanking on her thighs. Finally defeated, Lizzy lays back on the couch drinking her bottle, letting herself get distracted by her stuffed bunny while Step-Mommy changes her diaper and talks about how much of a big baby she is to Auntie Mandie.

After being put into a nice, fresh diaper, Auntie Mandie shares the surprise- training pants! But since Lizzy is such a baby, they have to go over her thick diaper. Baby Lizzy is so excited and smiles thinking she really is a big girl, while her Step-Mommy and Auntie laugh.

Finally, the baby girl is back to playing with her toys, while Step-Mommy Adriana and Auntie Mandie start dinner. It's never a dull moment with a diapered baby girl in your house!
