No, the baby hasn't leapt ahead by four months. I just read an interesting article by a statistician saying that the most babies are actually born in week 39. I thought that the anecdotes were correct, that first babies ARE always born late. But now I'm thinking... late July? That's MY birthday timeframe. (Though I am down with the idea of baby being a Leo, like me, and of M. having to live with a house full of felines!) Right now I will hold out for early August, though I bet in July I will have changed my tune!
