My 4yo is a child of the soil.
One bedtime last week we were answering the age old question of "Where do babies come from?".
I told him that Daddies plant seeds inside Mummies and a baby grows. He thought for a bit - "is it a carrot seed?" he asked. "No", I said "because that would grow a carrot". "Oh yes! I must be a baby seed". "Yes" I said. "That's good" he said - "because you can't grow carrots..."
(We then got onto the mechanics. After flatly dismissing the anatomical explaination of the "special cuddle" that Daddies give to Mummies he seems to have decided that Daddy keeps a magic wand in his trousers that he waved over Mummy. A trip to the magician will never seem the same again!)
On the gardening front after a week away in Brittany I am dusting off my courgette recipies.
