Come on! Really?

So I am extremely annoyed. It seems like we just get over one thing and then we get something else. Ayden got the flu for his birthday my poor boy. And last night Kadence and Makayla were up all night puking. I even had Kadence and Makayla get the flu shot and they still get it. Seriously? I keep my house clean, I keep things sanitized and I have my kids wash their hands and use germ-x and still we have been getting sick a lot this year! I don't know what else to do. I am just annoyed and frustrated.
