I love my yoghurt

Lina is absolutely crazy about yoghurt. She could eat it any time of the day in unlimited amounts. She knows the yoghurt is in the fridge, and therefore the fridge has become her best friend. Obviously we cannot allow Lina to only eat yoghurt, the whole day. So sometimes the fridge stays closed. For now, she does not yet have the strength to break it open. Although I am afraid not for long...
