By the end of the day most of the group were starting to tire. they had walked far to try and cram as much as possible into the trip and Bruce had wanted to see Yellowstone's Grand Canyon. Steve had forbidden Tony to fly everywhere and was beginning to regret the decision as the billionaire was walking slower than his three-year-old son.

Suddenly Stark stopped, an idea lighting up his eyes and dropped to his knee to rummage in his backpack. Triumphant, he held up a bag of Haribos and tore them open.

"Sugar! I need a sugar boost to keep up with these fitness freaks I live with. Anyone else?"

"Me, me, me, me, me!" Came the cries from the suddenly alert children and the sweets were soon demolished.

Five minutes later Max compared a passing tourist to a whale and he and Pip burst into a fit of giggles. Twenty seconds later Pip still hadn't stopped to breathe. As the laughter racked her body she knelt in the dirt, tears streaming down her face. One by one the group stopped and turned to watch. "Did you gave her sugar Tony?" Asked Natasha, who had been walking ahead with the other woman when the haribos were dispersed.

"It wasn't that many sweets!" Stark protested. "And my two are fine."

"Come on, Froglet." Clint said quietly as he slung his daughter over his shoulder in a fireman's lift.

"Your children aren't related to Clint Barton!" Natasha ranted at Tony. "Have you seen that man on a sugar high?" She turned to gesture at her husband and saw the way he was carrying Pip. "Clint! You'll make her sick!"

Clint rolled his eyes. "I'm carrying her upside down not swinging her around by her ankles." He argued but Natasha's glare didn't cool so he lifted Phillipa off his shoulder and balanced her on his hip in front of him. Everyone watched in amazement as Clint met his daughter's eyes and placed a finger on her lips. She immediately stopped laughing, hiccuped twice and fell silent. Clint kissed her hair and let her down. Phillipa took her father's hand and they started walking again.

"That is some insane parenting skills." Jane commented as they followed the little girl walk calmly beside her father.

"It's awful parenting skills." Natasha said sadly. "What kind of parents train their daughter for the field."

"That's for the field?" Jane asked, surprised.

"It means deadly silence now or someone will shoot us. Clint shouldn't have used it here. He better have told her there isn't anyone after us." Natasha stalked off to sort out her family and Jane turned to Pepper.

"Is their whole life like that?" She asked.

"24/7." Pepper told her. "Clint and Natasha have too many enemies to ever let their guards down, more than the Avengers as a team. Phillipa wasn't planned- everyone thought the Red Room had ended Natasha's chances. They never wanted her to live the same life as them but they trained her so she could fight if she was held hostage and as you would expect, Phillipa's a natural. It's no longer a question of if she will become an assassin but when."

Really short but I needed it out the way. I'm not going to try and do these age order any more, just ideas when i get them. Speaking of- I have a good one from when they are a bit older ready :)
