Well i'm not sure she has to but it's lovely she's doing it! It's healthy living this week at dd's pre school so the children are tasting different fruits and veg, having dancing lessons etc. Her lovely teacher has dressed up as a different fruit or vegetable every day for when the nursery children come into school. On Monday she was a strawberry, yesterday was the best so far as she was a pineapple and today she was a carrot. It's hilarious and the children love it. I'm so glad I chose this nursery for her and will be sad to leave it when we move.
