In "The Valentino Submergence", Howard and Bernie nurse a rabbit back to health that almost drowned in their hot tub looking very parental while doing it. After Howard heads to the emergency room, Bernadette tells the rabbit that she'll have to find another time to tell Howard that she's expecting. The rabbit didn't die, but that is also a cliche for being pregnant.
In "The Birthday Synchronicity", Bernadette gives birth and Howard announces that she had a girl. The baby is named Halley. Also it's Amy's birthday. The baby was named after Halley's Comet. Her cry is sounded like Mrs Wolowitz screaming.
In "The Holiday Summation", Halley is crying constantly and Bernadette doesn't know how to deal with it. She gets more upset when Stuart gets her to stop very quickly. Finally she solves the problem by crawling into Halley's crib and holding her while she sleeps.
In "The Romance Recalibration", Howard comes up with an over-complicated path to Halley's crib to avoid the squeaky floor board that were waking her up. He also hopes that she never has sex in her room like he did.
- She is named after Halley's comet.
- Her godfather is Raj.
- She has the same birthday as Amy, but in different years.
