My infant has just had her third stomach bug in three weeks!! My husband also had it twice. This is all on top of a nasty cough/cold we have all had for 8 days now. I did a little bit of sanitizing after the first round and then did everything I could the second round - ran all laundry through sanitizing cycles in the washing machine, bleached common surfaces, etc. i think I was pretty thorough. One thing I did think of - LO cosleeps with me and has puked on our bed almost every time she's been sick. Each time I strip the bed completely and wash everything on the sanitize cycle. But we don't have a waterproof mattress cover. Could the virus be living on the mattress and getting through the sheets and re-infecting her that way?? I'm so sick with a cold on top of all the stomach bug stuff that I'm totally falling apart. I've cried several times today. Any helpful tips for killing this stomach bug are welcome.
