Separated: The twins shared a chest wall, diaphragm, pericardium and liver but are now expected to live 'full, healthy and independent lives'
Ho ho ho: The twins celebrate their first Christmas by getting their picture taken with Santa after their successful surgery
Relief: Shellie Tucker, pictured with Allison and Amelia, expressed her joy on her blog after the operation
