Lynn-What a nightmare you had to go through at your son's nursery school! I feared that very thing happening to my daughter. Luckily, the day she vomitted, it was before school, so I din't send her. When my daughter was 1 year old, I was planning on returning to work. The only daycare center near my job was reluctant to take her. They finally agreed, but I just wasn't comfortable. I ended up giving up my job-which was a good thing for my daughter-there have been alot of trips to the doctor and hospital. We truly have to be advocates for our children.
