The Big Bang Theory' season 10 episode 11 is entitled "The Birthday Synchronicity." The episode is about Amy seducing her boyfriend Sheldon for a birthday sex. However, her sexy surprise is about to be interrupted by the arrival of Bernadette and Howard's baby.

Let us recall, Amy's birthday is a special one as she and Sheldon (Jim Parsons) have created a tradition of it. The two had their thing for the first time during Amy's birthday in the previous season. Since then, they decided to have sex at least once a year on the same date.

In episode 11 of "The Big Bang Theory" Season 10 Sheldon will wake Amy up by midnight to greet her a happy birthday. He will give her an eccentric gift-an MRI scan of Sheldon's bra. Sheldon will explain that one part of his brain is always thinking of her and Amy will love it.

The couple will start having intimate moments but it will be interrupted by Leonard  and Penny who will knock at their door and  announce that  Bernadette and Howard are going to have their baby, but turned out to be a false alarm because a nurse sent Howard, Raj, and Stuart home.  Amy, Sheldon, Leonard and Penny went to their respective homes but apparently, Raj interrupts again and announces that Bernadette is having the baby.

According to Variety, showrunner, Steven Molaro revealed that they wanted Bernadette to finally give birth in the incoming episode saying that she had been pregnant for 11 months now based on the series' actual timeline. "We figured she ought to have this baby pretty soon."

Unfortunately, The Big Bang Theory" fans will have to wait for a few days to catch season 10 episode 11 as the air schedule has been changed. Instead of going up in CBS on Thursday, Dec. 8, the new episode will air on Dec. 15. Viewers should stay tuned for this as this episode will finally show the arrival of Bernadette (Melissa ) and Howard's (Simon ) baby.
