I seriously have the best mother in law in the world. I'm flying out tonight to Illinois from California for a solid week , because my father is in bad health. I've been super sick, I had to throw a baby shower last night (45 people showed up! 😣) and too top it all off, I have to be away from my daughter for 7 days. Luckily, my mother in law is flying in to stay with my husband and baby for the week while I'm gone. My poor husband has to work all week, so she's going to be staying and helping out. I just love her to death. I'm so not looking forward to flying while sick. Any advice so I don't sneeze and cough the entire 4 hour flight?? 😷
