"Hurrah. This might be cold." Chummy squeezed some sort of gel onto her stomach and moved the wand around. "Bit hard to get the hang of, actually. But if you can manage it, you can - ah! There. See that little shape there, Mrs Pontmercy? That's baby."
Trixie gaped. "Chummy that's amazing!" She beamed at Cosette. "And you, too. And is that the heartbeat?"
Chummy nodded. "It is. Gets a bit noisy, though, and I still prefer the pinard for that - but I imagine if you used this to find out the position and then the pinard, it would be very effective. All looks absolutely splendid, Mrs Pontmercy. I can even print a picture for you."
Trixie beamed. "You can come back for regular checkups. Every month or so for now, unless you have any questions, of course. We'll take good care of you and this little one."
