Kids especially really young ones can catch bugs that adults fequently escape so it is very possible that you will not get it if you haven't already had it. It is also possible for the same virus to have a different effect on you than it did on your child. I think it is just in some peoples nature to throw up when they get a stomachh virus (I am one of them) my Mother on the other hand could get the same virus I had and never throw up from it. It is very possible for you to both get it at the same time. I know several people that has happened to and it has happened in my own family as well.
