I'm grouchy and I constantly have butterflies in my stomach......I HATE THIS!!!...my son is in kindergarten, when I picked him up today, he told me a classmate was "really sick"...his tummy hurt and he went to the health room and never came back!...I know it could be other causes than an sv, but my mind won't stop thinking otherwise....I fell like he's going to get sick and throw up...i'm so scared!!!These sv's seem to be so prevalent nowadays, that i'm sure it's coming anyday now....HELP......what do you parents do to get through the school year day after day, without so much worrying??..Please anyone, I want to be happy and worry free!
