how to not get sick when your around sick people all the time?!

Here's what you should do, avoid anything they may and might've touched. And also if you can't avoid it, then don't touch your face too much either. The reason almost everyone gets sick by close contamination is because they would usually touch their face (mostly eyes, nose or mouth) to either rub something off or just 'cause they get board when they really don't realize thats how they get sick themselves. So avoid touching your face! Next make sure they don't cough on you of course. Also eat some vitamin c like orange or apple juice 'cause like everyone else says it helps strenghten your immune system. And since your mom babysits them, try and wash your hands as often as you can with soap and warm water. that also helps kill the germs that might infect you from your hands.

Wash your hands a lot! wash hands wash hands, thats what you need to do, just wash those hands! dont touch your face, or your mouth, DONT USE HAND SANITIZER, IT KILLS THE GOOD BACTERIA AND DOESNT HELP ONE BIT. dont share cups or anything, healthy diet!
