That made sense that it was new or else Tavie believed she knew Di well enough that she ought to have spotted the difference in her sister long before. You didn't know someone your whole life without learning how to read them.

But then again,  she also knew little about pregnancy and babies so maybe that would have canceled out get knowledge of her sister. As the youngest, she'd never been that close to pregnancy. Maybe Aumt Hermonie but she'd been far to young at her aunt's last child. Mairda maybe but and never been close to her brother's wife.

"Oh, I suppose that is why most women stay home during pregnancy. I would love children one day but I should miss the balls. Oh but it will all be worth it in the end. They'll be so cute!"
