Siblings Brennen Heisserer and Bailey Heisserer pose for their mother on the first day of school Thursday before entering Kelso C-7 Elementary School in New Hamburg. Several other schools in the area resumed classes Thursday including the Sikeston R-6 School District where the first day of school had a few tears shed in the morning, school officials said. However by the afternoon, tears had given way to smiles and shouts at recess.
