If you are after yoghurt ice lollies, you can make them really easily yourself... Simply get some small sticks (popsicles sticks, thick non-pointy skewers, straws, etc) and poke them into the tops of small yoghurt pots (right through the foil tops). Place them carefully in the freezer, let freeze and voila! Obviously not as transportable as the snazzy pre-packed ones, but a lot less expensive!
