"Sippy Cup" is a song by American recording artist Melanie Martinez as the third single from her debut album, Cry Baby. A music video featuring fashion designer Stella Rose Saint Clair was released July 31, 2015.

In the interview with SPIN, Melanie described Sippy Cup as the second part to Dollhouse. "The song is basically the bridge between the Dollhouse EP and the Cry Baby album. This song is about what actually “goes down in the kitchen,” a deeper look into Crybaby’s family life. This is my favorite video I’ve done so far. Directing this music video made me very excited to direct videos for every single song on the album. I can't wait to continue telling the story of the album in every way possible."

Melanie opens Cry Baby’s walls a little further in “Sippy Cup.” We get to see just how serious her parents’ problems are. No matter how much her mother tries to hide her alcoholism, Cry Baby knows that she is hiding liquor in her sippy cup. When the drunk mother sees her husband with another woman, she murders both of them only to have Cry Baby walk in on the crime scene. To cover up the murder, her mother drugged her so she would forget the gruesome memory.
