Raph
When he's sick he'll try and continue his older brotherly duties but end uo=p in bed. He tries and continue keeping peace in the lair but can't. He has a very stuffy nose so his room is filled with tissue boxes and dirty tissues. Favorite soup is veggie. Once he gets better he goes back to his brotherly duties.
Leo
Will pretend he's not sick until he is on the verge of passing out. His nose gets ever red when he's sick (Like his stripes) He gets very needy and demands attention(more than usual) His throat gets clogged up and his voice sounds weird. His favorite soup to eat is carrot soup.
Donnie
Being the doctor of the family he knows when he's sick and will mostly take care of himself. Though some turtles...wil try and sneak in to see him. He pushes them out not wanting them to get sick. He likes to have chicken soup
Y/n
She sleeps through it. Splinter has to wake her up to give her the medicine and for her to eat the soup but after that she'll immediately go back to sleep.She'll sleep talk and ger brothers record when she says the stupidest things. She doesn't care what type of soup she gets cuz she never remembers once she's better.
Mikey
When he gets sick he gets all grumpy and will be rude. He hates taking medicine and will even hide to try and avoid drinking it. He also hates eating soup and will only eat egg soup. Once he's better he'll apologize for being a grump and give pictures as a form of apologize
