Calvin's first real word

He said it on the weekend and I thought it was just fluke, but this morning when I picked him up, I said, "Let's have some breakfast Calvin". And he looked at me, so I said, "lunch", and he said to me, "lunch". So there it is - Calvin's first word, other than "mummy, daddy, and nanny", is "lunch". I think he might also be on the verge of "'nana" (as in 'banana'), but we'll see.
My child is a genius !
