4 months later...

Kate was now twenty weeks pregnant.

Kate and Castle were both at the breakfast table eating their breakfast, today was the day that they were going to find out the gender of their baby. Both, Kate and Castle have been waiting for this day to come. they couldn't wait until their five thirty appointment with Dr. Chandler.

" Can you believe we are going to find out our baby's gender today Castle?" Kate asked.

" - I know it's so surreal" Castle replied. Castle himself has been waiting for this day to come. Ever since, Kate told him that they were having a baby together he has been over the moon. The thought of finding out the gender of his and Kate's baby today, feels like a dream to him. There was a time when, Castle thought he never find love again. After his two marriages failed, Castle felt that finding his true love was pointless. Then, upon meeting Kate he couldn't have felt more wrong. Because, at his book signing event there before him stood the most beautiful woman he had ever seen.

Kate looked at Castle curiously, she could see the off look in Castle's eyes. Kate knew that, if Castle's was looking that far off that usually meant he was in deep thought.

" What you thinking about?" Kate asked.

Castle looked Kate in the eyes and smiled at her. Because, let's face it Richard Castle was so in love with Kate Beckett.

" - I was thinking back when the first time you and I met" Castle replied. He looked to Kate and his heart instantly melted. He knew from the moment he met Kate, that she would be his forever. He also knew, that him and Kate would soon after that be raising a family. So, now here they were about to have their baby in only months time.

" - I remember that day as well" Kate smiled.

Kate and Castle looked at each other, they couldn't wait to find out the gender of their baby today.

Five thirty came around, Kate and Castle were in the waiting room of the doctor's office. This was it, they were finally going to find out the gender to their child. The nurse led Kate and Castle to a room, where Kate could put on her gown and lie down on the bed. The nurse left the room, so Kate could have some privacy to get dressed.

Kate and Castle both were very nervous, - after all they were about to see their baby's progression. And, find out what their baby's gender is. they both heard a knock on the door.

" Come in" Kate answered.

The door opened, in walked the doctor with the sonogram machine. Kate and Castle were grinning from ear to ear, this was it. This is the moment they get to find out their baby's gender.

" -Hello there" Dr. Chandler said with a smile on his face.

" -Hello doctor" Kate replied.

Dr. Chandler set up the sonogram machine, he then put the jelly on Kate's stomach. then, there up on the screen was the picture of Kate and Castle's baby.

Kate and Castle both looked at the screen, they both were so amazed that something so tiny could bring so much joy.

"Look Castle, there's our little miracle" Kate said.

Castle looked to Kate and nodded and smiled, he had no words to describe how he was feeling at the moment.

" Would you like to hear the heartbeat?" Dr. Chandler asked.

" Yes" Kate and Castle said at the same time.

Dr. Chandler turned up the sound on the machine, there Kate and Castle heard the heartbeat of their child. Hearing their child's heartbeat, was like a weight lifted from their shoulders. It brought them so much joy and happiness, that they didn't know how much happier they could get.

" Would you like to know the gender of your baby?" Dr. Chandler asked the couple.

" Yes" Kate and Castle replied together.

Dr. Chandler nodded, he looked at the screen on the sonogram and looked to the happy couple.

Congratulations Dr. Chandler replied.

You are having a baby girl.
