Peter was hungry and Pepper was gone. He had woken up from his nap two hours ago and played 'I Spy' with JARVIS for a while, but now he was hungry. Fortunately for him, he found his dad in his lab, tinkering around with music blaring through his speakers.

Peter tried opening the door, but it didn't budge. He frowned and tried pulling it again. Still nothing. When he tried knocking, his dad didn't seem to hear him over the music. He was about to bang louder when JARVIS asked if he wanted in. Peter said he did and the door unlocked as JARVIS turned Tony's music down.

"Hey, Peter," Tony said, smiling when he saw his son walking into his lab.

Peter stared with wide eyes up at all the Iron Man suits as Tony scooped him up into his arms.

"What's up, kiddo?"

"I'm hungry," Peter said, turning to face his dad.

Tony glanced at his watch, noticing it was almost five o'clock, then nodded.

"Alright," he replied. He adjusted his grip on Peter and told JARVIS to shut down the lab. "How do sandwiches sound?" he asked, carrying Peter upstairs and into the kitchen.

"Yummy!" Peter exclaimed.

Tony set Peter on a stool and turned to grab some bread. He wasn't particularly talented at making food yet. He had been trying harder now that he had a son, but he still wasn't very good. Besides, he wasn't in the mood for a big meal.

"Strawberry or grape jelly?" Tony asked, opening the fridge and grabbing the peanut butter.

"Strawberry!" Peter cheered.

Tony grinned and nodded, grabbing the strawberry jelly out of the fridge as well.

"Good choice."

He grabbed a knife and quickly spread peanut butter on two bread slices. After spreading the jelly on the other two slices, he put the sandwiches together and handed one to Peter. With a small giggle, Peter took it and bit down. Almost immediately he started choking.

"Daddy!" Peter cried, dropping his sandwich. Tony dropped his as well and grabbed Peter.

"JARVIS?" Tony asked, panicking as he rushed to the lift and went down to the medical floor.

"Peter seems to be having an anaphylactic reaction to the peanut butter," JARVIS told him.

Tony rushed out of the lift as soon as the doors cracked open and raced towards a nurse.

"Peanut butter... anaphylactic..." that was all Tony could get out, but the nurse understood and yelled for a doctor. She took Tony into a room where he tried to lay Peter on the bed, but Peter latched onto him, refusing to let go as tears of panic raced down his face.

"Honey, you have to let go so we can help you," the nurse told him kindly.

Stepping back, Tony grabbed Peter's hand and watched helplessly as doctors surrounded him, rushing to stop the reaction.

* * * * *

It felt like years before Tony was told Peter was going to be okay. The doctors had shoved him out of the room when the reaction got worse and he had been waiting for hours for news on Peter. When a nurse finally said he could go back and sit with him, Tony all but ran to his room. Peter was still unconscious when he got there, but the nurse said he should wake up soon.

"Once he's awake, come to the front desk and we can check him out," she said. Tony nodded but didn't look away from Peter.

Ten minutes later, Peter finally opened his eyes.

"Daddy?"

"Yeah, buddy," Tony said softly, moving closer to Peter. "I'm right here."

"That was scary," Peter whispered and Tony nodded. "I don't want to do that again."

"We'll try," Tony promised.

Peter nodded and let Tony pick him up to carry him to the front desk. The nurse explained that Peter was severely allergic to peanuts and after a couple of tests, they discovered it was all nuts. She gave Tony an epi-pen and told him how to use it.

"Thank you," he said when she was done. She nodded in reply and Tony carried Peter back to the lift and upstairs.

Peter was left in his room while Tony cleaned the entire kitchen. He threw away anything that had nuts in it or if it so much as said it may contain them. In the end, most of their food was thrown out and Tony could be found deep cleaning the kitchen. Pepper frowned, watching him for a moment before saying anything.

"What's going on?" she asked. Tony jumped and looked up at her.

"Peter's allergic to nuts and peanuts," he said.

He explained what happened and that he had thrown almost all the food out. Although Pepper thought it was a little over the top, she didn't hesitate to go check on Peter after Tony told her what had happened. When she peered into his room, he was fast asleep on his bed, still fully dressed. She closed his door and returned to the kitchen where Tony was still cleaning.

"I'll clear the rest of the Tower out tomorrow," she promised.

Tony nodded, not looking up from where he was scrubbing the counter. There was no way Peter was ever going to come across peanuts if Tony had anything to do about it.
