In this chapter; Evie is 13, Elijah & Henry are 10, Alexis is five, Cecelia is four, Jacob is nine and Oliver is five and Poppy is 3 months old

Natasha was taking complete advantage of being alone in the tower; it didn't happen very often!
She had a quiet, relaxing morning and did some tidying in the afternoon.

Suddenly she felt a tightening in her abdomen; she passed them off as Braxton Hicks contractions and took it as a sign she needed to rest, but an hour later when they were coming more rapidly and had increased in intensity she couldn't deny it any longer; she was in labour. She was only 33 weeks pregnant which worried her, what worried her more was that everyone was out of state; Clint, Tony and Pepper had taken all the kids to Disney World for the weekend, Thor and Jane had gone along and Steve and Bruce had been posted in Texas temporarily for the past few days.

She rang Clint, who promised they'd be back as soon as possible; he'd made Fury lend them a jet in case of an emergency. It'd take them less than 2 hours to get back, Jane also though Darcy may be in the city and told Natasha to try her cell. Luckily for her, she wasn't far from the tower and sped right over.

"Tasha? Natasha?" Darcy had sped through three red lights to get to the tower and been impatiently jabbing at buttons in the elevator. She found Natasha curled up on the couch, she was in serious pain and worry was etched all over her face.

"Come on Nat, we need to get you to medical now"

"No, we need to wait for Clint"

"I don't think we do, he can meet us there. I am so not qualified to deliver a baby!"

When they got to SHIELD medical the doctor on shift tried to send her away, blaming Braxton Hicks once again.

"She's had five children! Don't you think she knows the difference?" Darcy yelled. She scared the doctor so much he gave in, admitted her, and call the resident OBGYN in right in the middle of her week off.

Darcy stayed with Natasha, gripping her hand through the contractions and wiping her hair from her face. "Clint will be here soon" she kept promising, keeping her eye on her phone for any update.

"It's time to start pushing" the doctor informed her

"But Clint's not here"

"This baby isn't waiting for anyone"

At that moment Clint burst through the door

"Oh thank God!" Darcy said, "Good luck Tasha!" She said, kissing her friend on the forehead before leaving the room and joining the others in the waiting room.

"Sorry I'm late!" Clint scurried to take up his place by his wife's side, taking her hand in his he smiled encouragingly at her

Just over half an hour later their son was born. He was so tiny, but perfect.

Clint went to announce the news to the rest of the family eagerly waiting outside, while the baby was checked over and transferred to NICU for observations due to his size.

"We have a son" Clint announced proudly, "his name is Isaac Anthony Barton" he watched as Tony's face lit up in disbelief. "It was all Natasha's idea" he added quietly to him

Everyone crowded round; offering their congratulations and asking after Natasha. Bruce and Steve suddenly burst through the door, joining the huddle; desperate for an update.

"Agent Barton?"

Clint turned to see the doctor gesturing him to follow her back down to Natasha's room. A nervous glance at the others told him they were all thinking the same thing: Natasha had had problems in the past; following Evie's birth Natasha had almost died, the boys were born following complications of twin-to-twin transfusion syndrome, Alexis was born almost three weeks overdue, and Cecelia had been breech; none of them had been straightforward. The fact that Isaac had been almost two months premature had been worry enough.

Clint immediately sprinted back down the hallway to his wife's room.
