Never Ending Sickness!

We'll our household has been sick it seems like for over a month now. We have had everything you can think of. Over a week ago, I started with a Sinus infection that went into bronchittis & pneumonia. Then last weekend Jeff started getting sick and he ended up with a sinus infection, double ear infection, bronchittis and pneumonia. He is just now getting over it and now Chloe has it. She started running a fever last night and complaining with her throat hurting. So I took her to the Little Clinic today and she has the start of bronchittis and pneumonia. I am so tired of us being sick. I just want to know will it ever end???
