Previously in "Harry gets sick"
"Put him down here and I'll take a look at him." Lily struggled with our son for a while. Before I took him and told him softly but sternly that he had to lie down otherwise he would be sick forever. I had never seen our son scramble out of my arms faster. He lay down and I crouched down next to him and took is small hand.
I stayed in that position until Madame Pomfrey pulled Lily aside.
"Well it is not strep throat, but a very bad case of the stomach flu. I would like to keep him here for a few hours to make sure he won't take a turn for the worse. You and James are welcome to stay; Professor Dumbledore would like to talk to you about Order Business." I heard her tell Lily. All of a sudden Harry threw up. Madame Pomfrey swooped in with a bucket to catch it and I rubbed his back soothingly. When he finished I wiped his face off and hugged him close to my chest. "Shhh, Shhh, Daddy's here. I gotcha, you're going to be okay, don't cry." I whispered into his ear.
"Daddy I don't like throwing up" Harry said into my chest.
"I know, I know, nobody likes throwing up. I don't like throwing up and mummy doesn't like it."
"Harry were going to have to stay here for a little bit so you don't throw up and Poppy can give you some medicine."
"But I don't like being here Mummy." He said simply his bright green eyes filled with innocence and fear.
"Did you know that Daddy spent a lot of time here when he was at school?" Lily said taking him from me. My son looked at his mother to me then back to his mother in disbelief slowly he shook his head no. Lily then proceeded to tell him about the time I got my ribs crushed by a bludger.
