My mother in law called me tonight to ask me if I had any phenergan. My nephew started throwing up and having diarrhea this evening. My children were around him last night!!!! His twin sister was here at my house tonight, and I was giving her kisses. I am worried that my nephew was contagious last night, or that my niece is contagious, but just isnt feeling bad yet. I hate this, I do so well with my emet, until I hear something like this.
