Leaning right over, I manage to grab the ultrasound stick. I apply it to the gel on my stomach — and at once the blurry image reappears on the screen.

I did it! Now I just have to shift it slightly to get the crucial bit…. Frowning with concentration, I move the probe around on my abdomen, tilting it this way and that, craning my neck to see the screen. This is a lot easier than I thought! Maybe I should become a sonographer. I’m obviously a bit of a natural—

There’s the head. Wow, it’s huge! And that bit must be—

My hand freezes and I catch my breath. I’ve just spotted it. I’ve seen the sex of our baby!

It’s a boy!

The image isn’t quite as good as the sonographer’s — but even so, it’s unmistakable. Luke and I are going to have a son!

“Hello,” I say aloud to the screen, my voice cracking slightly. “Hello, little boy!”

And now I can’t stop the tears rolling down my cheeks. We’re having a gorgeous baby boy! I can dress him up in cute overalls, and buy him a pedal car, and Luke can play cricket with him, and we can call him—

Oh my God. What are we going to call him?

I wonder if Luke would go for Birkin. Then I could get a Birkin to be his nappy bag.

Birkin Brandon. That’s quite cool.

“Hi, little baby,” I croon gently to the big round head on the screen. “Do you want to be called Birkin?”

“What are you doing?” The sonographer’s voice makes me jump. She’s standing at the door with Luke, looking appalled. “That’s hospital equipment! You shouldn’t be touching it!”

“I’m sorry,” I say, wiping my eyes. “But I just had to have another quick look. Luke, I’m talking to our baby. It’s just…amazing.”

“Let me see!” Luke’s eyes light up, and he hurries across the room, followed by the sonographer. “Where?”

I don’t care if Luke sees it’s a boy and the surprise is ruined. I have to share this precious moment with him.

“Look, there’s the head!” I point. “Hello, darling!”

“Where’s its face?” Luke sounds a bit perturbed.

“Dunno. Round the other side.” I give a little wave. “It’s Mummy and Daddy here! And we love you very—”

“Mrs. Brandon.” The sonographer cuts me off. “You’re talking to your bladder.”

Well, how was I supposed to know it was my bladder? It looked just like a baby.

As we walk into the consultant obstetrician’s room, I’m still feeling rather hot about the cheeks. The sonographer gave me this huge great lecture about how I could have done damage to myself or broken the machine, and we only managed to get away after Luke promised a big donation to the scanner appeal.

And, she said, since I hadn’t been anywhere near the baby, it was very unlikely I’d seen the sex. Hmph.

But as I sit down opposite Dr. Braine, our obstetrician, I feel myself start to cheer up. He’s such a reassuring man, Dr. Braine. He’s in his sixties, with graying, well-groomed hair and a pin-stripe suit and a faint aroma of old-fashioned aftershave. And he’s delivered thousands of babies, including Luke! To be honest, I can’t really imagine Luke’s mother Elinor giving birth, but I guess it must have happened somehow. And as soon as we discovered I was pregnant, Luke said we had to find out if Dr. Braine was still practicing, because he was the best in the country.

“Dear boy.” He shakes Luke’s hand warmly. “How are you?”

“Very well indeed.” Luke sits down beside me. “And how’s David?”

Luke went to school with Dr. Braine’s son and always asks after him when we meet.

There’s silence as Dr. Braine considers the question. This is the only thing I find a tad annoying about him. He mulls over everything you say as though it’s of the greatest importance, whereas you were actually just making some random remark to keep the conversation going. At our last appointment I asked where he had bought his tie, and he thought about it for five minutes, then phoned his wife to check, and it was all a total saga. And I didn’t even like the stupid tie.

“David’s very well,” he says at last, nodding. “He sends his regards.” There’s another pause as he peruses the sheet from the sonographer. “Very good,” he says eventually. “Everything’s in order. How are you feeling, Rebecca?”

“Oh, I’m fine!” I say. “Happy that the baby’s all right.”

“You’re still working full-time, I see.” Dr. Braine glances at my form. “And that’s not too demanding for you?”
