Sorry for the delay am currently working three jobs and just got my first day off in a couple of months!

Enjoy!

Harry was eating dinner when it happened, it was only half past ten and he was curled up on the sofa with Mummy watching a film when his Daddy came through the door,

"DADDY" he yelled and ran to greet the man. Harry lifted his hands in the air to be picked up but frowned when Daddy simply walked past him up the stairs.

"Sev!" Cassie called confused at what her husband was doing home so early.

"Stay here Harry" Cassie told him as she walked up the stairs to follow her husband.

"Sev, what's happened? Why are you home so early?" Cassie asked worriedly as she sat beside her husband on their bed, Severus had his head in his hands bent right over.

"Migraine" he whispered as he attempted to curl up on the bed.

"Do you want a potion?" Cassie asked in a whisper as she pulled the curtains and dimmed the lights.

"Yes please… O God" Severus moaned as he ran to the en suite and began throwing up, as she turned to grab a potion she noticed a very concerned looking boy stood at the doorway watching his father throwing up.

"Daddy sick?" Harry asked with tears in his eyes. Cassie nodded and Harry scuffed his feet on the carpet paying them great attention.

"Is Daddy gonna die?" he asked sounding heartbroken.

Cassie wasn't sure if she was going to laugh or cry, instead she picked up her son and carried him downstairs. "Daddys not going to die sweetheart he's just a little poorly today, let's make him feel better." Cassie told her son as she shifted him to her hip in order to maneuverer them both into the potions lab to gather the necessary potions. As she carried Harry and the potions back up to her husband she saw her husband coming out of the bathroom.

"I think I have muggle chicken pox" he told his wife as he stumbled out of the bathroom removing layers of clothing as he made his way into bed. "We need to keep the kids away, only you and Toby have had it, Harry, Daddy will be fine in a week or two. He just needs some rest ok, you make sure you listen to Mummy!" Severus told him before falling asleep. Cassie kissed her sons head and carried him downstairs closing the door behind them to leave her husband in peace.

The day was tense in the Snape house, Harry was moping around, not being allowed to see his Daddy, Lily and Charlie were playing game which he was too little for, Toby was in his dorms and Mummy was cooking dinner. Harry hated not being able to see his Daddy, Daddy always made everything better. He sat and sulked in the living room until dinner and didn't eat much, Cassie was getting more worried about the boy, but there was nothing that could be done so she let him sulk and hoped that he would open up to her soon.

The next day however Harry's rebellion picked up the pace and he was cranky and unpleasant all day, he kicked and whined in his pushchair all the way to school and then when he got home he turned over his toy box and threw and kicked all his toys. Before sobbing breathlessly in Cassies arms as she held him tightly. After the breakdown Cassie had spent all day carrying Harry around who would kick up a fuss if she even attempted to put him down. By the time Charlie and Lily were coming out of school Cassie was getting very tired and had recruited Toby to help with dinner and bedtime duty.

At bedtime it was Charlie's turn for rebellion and as Cassie tried to get him to go to sleep he sat and cried on her feeling tired and missing his Daddy reading his bedtime story, that night Cassie fell asleep on Charlies bed with Charlie and Harry sleeping on top of her and Lily asleep beside her.

As she got dressed that morning Severus woke up. "How are the kids?" he asked looking slightly feverish, "Is Toby in the dorms?"

Cassie turned to him and sat down on their bed brushing her husband's fringe from his eyes. "Harrys been clinging to me for twenty four hours and is currently sobbing onto a house elf downstairs, Charlie is sulking on his bed refusing to eat his breakfast, Lily is trying to persuade me she's too ill to go to school and Toby has a black eye after trying to bathe Harry this morning after Harry had an accident and that's just this morning" Cassie sighed. "They miss you Severus, and I miss you too. Get better soon" with a kiss to his forehead she finished getting dressed.

"Bubble charm them and bring them up" he grumbled, I'm not throwing up anymore just head ache and itchy, bubble charm should be fine." He put his hand up to his wife who was about to argue, "Just do it Cassie" he asked. Cassie nodded her head and went to make sure her children were indeed doing what they should be. After telling them all that once they were ready they would be able to say goodbye to their Daddy Charlie, Toby and Lily were dressed and busy eating but Harry was yet to move from the sofa where he was sat with a blanket clutched in the hand where his thumb was in his mouth being sucked on. His stuffed crocodile was in his other hand and no amount of coaxing was getting him to the table.

Cassie kissed her eldest goodbye as he left to prepare for his first class of the morning and called Lily and Charlie to take them upstairs to say goodbye. Harry followed but Cassie crouched down to his level and got serious with him. "Harry you haven't done anything I've asked this morning so you won't get to see your Daddy until you do. Harrys face crumbled and his face went red, his little legs went up and down until he was angrily running on the spot in anger and hurt. He watched as Mummy took Lily and Charlie upstairs where they were able to say goodbye, when they came back downstairs Harry was forced into his pushchair and given his sippy cup which was full of milk which after first not wanting it realised that he was very thirsty from all his crying and slurped on it in his pushchair on the way to school.

Once Lily and Charlie were dropped off Cassie felt exhausted and ran her hands through her hair peering at Harry who had fallen asleep on the ride to school. "Is he not well?" one of the other parents asked her, "He's fine, he's just had a morning of temper tantrums, Severus has got chicken pox and the kids haven't seen him in a couple of days, things are starting to get a little tense. I suppose I should get him home and dressed before lunchtime." She said tiredly and with a fond goodbye to the other parents she left to start another day with her angry three year old and sick husband.

At home she changed the still sleeping Harry out of his night time clothes and into his day wear before waking him and carrying the still drowsy boy upstairs and with a quick charm she opened the door to the master bedroom and deposited her son beside his sleeping father who cuddled each other in sleep before leaving their breakfasts on the side and starting her housework.

The sight that greeted her was worth the risk to her young son, Severus was lying awake smiling and entertaining their giggling three year old who was rolling around on the bed giggling. "Looks like you two are having fun!" she commented.

"MUMMY" he grinned as he sat up grabbing at himself awkwardly.

"Go to the toilet Harry" she ordered and after a slight hesitation he left leaving Severus and Cassandra to sit on their bed sharing a kiss.

"How are you feeling?" she asked when they finally broke apart.

"Itchy, but better, Harry's helped a bit with that." Severus said brightly as his son came barrelling through their door,

"Flush and hands Harry" his Daddy chided and he stomped off to the bathroom to perform the tasks.

That afternoon the three Snapes napped together before a phone call interrupted them, Cassie sat up and answered. "Hello" she spoke.

"Hello this is Mrs Wadebridge from Charlie's school, we thing Charlie might be feeling unwell, we were wondering if you would be able to come and pick him up?"

"Yes of course" Cassie told the school nurse slipping her shoes and coat on as she talked. "I will be down as soon as I can" she said and hung up the phone.

Cassie gently woke her husband and told him what was happening and that she had to leave to pick Charlie up, "leave Harry here" he said "we''ll be okay for twenty minutes without you." And with a nod and a kiss the epidemic started. Over the next three weeks Charlie, then Lily and eventually Harry all managed to end up with Chicken pox but none of them were too concerned as they were all allowed into the master bed to sleep as a family and spend the days snuggle on the sofa together.
