Meredith gripped the side of the car door, as they waited in traffic on the high way. She closed her eyes exhaling slowly. Derek had once asked Meredith what a contraction felt like when she was pregnant with Liam, she said the best way to describe it is two bones rubbing up against each-other. Meredith was brought back to reality when a harsh contraction overtook her body, causing her to cry out in pain.

"Hang in there Mere, the freeway's clearing up a little." said Derek as he let her squeeze his hand.

"Derek we're not going to make it the contractions are too close." said Meredith as she let moaned in pain. "The hospital is still twenty minutes away. We're not going to make it.

Derek's face looked slightly panicked. He made sure not to show it though. "Mere we're going to make it. I promise. Look we're already moving." said Derek as they started to drive clearly down the high way.

"We're not going to make it." protested Meredith.

"Why not?" asked Derek as her continued to hold her hand as he drove.

"Because I have to push."

Addison walked over to the nurse's station where she saw Mark sitting behind the desk feeding Anna. She smiled slightly before continuing over.

"Hey." said Addison. "Have Meredith and Derek come in yet?" said Addison as he tickled the baby's foot.

"Not yet. Izzie told me to look out for them, sine she had to go into an emergency surgery." said Mark as continued to feed his daughter.

"It wouldn't take this long to get to the hospital from their house would it?" asked Addison.

"Maybe they're stuck in traffic?" suggested Mark.

"No I don't like how close Meredith's contractions were when Derek called. I'm going to look for them." said Addison grabbing her coat and quickly heading out f the hospital.

Meredith had her arms wrapped around Derek's neck as he moved her to the back seat. They both then heard a familiar voice.

"Meredith? Derek? What's going on?" asked Addison as she quickly ran up to them.

"My contractions are too close." said Meredith as she cried out in pain. "Addie I can't have this baby out here. It's pouring." said Meredith as realization sunk in and she started panicking.

"Meredith... I promise you and your baby are going to be completely fine. Derek go into my car and get the emergency medical bag." said Addison as she tossed Derek the keys.

"Addison I can't do this... not here… what if something goes wrong?" asked a panic stricken Meredith. "Where's Derek? I need Derek." said Meredith as she looked around in alarm for him.

"I'm right here Mere." said Derek as he gave Addison the bad and pushes down on the seats in the car so it was all flat and got behind Meredith. "Everything's going to be fine." reassured Derek as he kissed Meredith's forehead.

"Meredith I'm going to examine you okay?" said Addison as she quickly pulled on her gloves and examined Meredith. Her eye's immediately lit up in surprise. "Meredith the head is crowing already. A few pushes and she'll be out. On your next contraction I want you to push.

Meredith nodded as she felt her contraction build up and she pushed, for ten whole seconds. She let out a gasp as she stopped. "It hurts." whimpered Meredith.

"I know it does." said Derek as he pushed her hair out of her face. "But its almost over." he said as he kissed her forehead.

"He's right Meredith, the head's out already. One more really good push and you'll have your baby." said Addison as she took a baby blanket Meredith had brought in her overnight bag and laid it on her chest." You ready?" asked Addison.

Meredith nodded and pushed hard until she felt the baby slip out and she heard a tiny soft cry.

"She's out." said Addison as she suctioned the baby's mouth with the instrument from the emergency medical bag.

"She?" said Meredith as the baby was placed on her chest.

"Congratulations you two, you have another daughter." said Addison as she smiled.

Derek peered over Meredith's shoulder to get a better look at his newborn daughter crying.

"She's here." whispered Meredith as she rubbed the baby with the blanket.

"She's here."

Meredith lay in a hospital bed later that night, in her own clothes and watched as Derek held their newborn daughter in his arms.

"She's perfect." said Meredith as stroked her daughter's cheek.

"She is. I think she needs a name though." said Derek as he smiled at Meredith.

"How about Madison?" suggested Meredith.

"That's a pretty name. What about Kate for the middle name?" asked Derek.

"After your grandmother?" said Meredith with a smile.

"I think it fits." said Derek as the baby yawned.

"Me too." said Meredith as she lay her head on Derek's shoulder and watched her daughter.

"Welcome to the world Madison Kate Shepherd."
