Soup freezes really well. To portion out for little ones, spoon into a mini muffin tin. It's the perfect size for a baby portion. Once all the compartments are full, cover the tray with cling film and freeze until solid (about 4 hours). Rub a warm cloth under the tray and the soup portions should pop out. Immediately add to a freezer bag, label and freeze. The soup should defrost in less than 30 minutes at room temperature and can be reheated in the microwave in less than 1 minute. Stir well and ensure it is warm the whole way though and not too hot for little mouths.
