"Her sister, Natalie, who also was conceived through in-vitro fertilization, in 1999 became the first "test-tube" baby to give birth."
Doesn't that contradict the main point of the story?

[Almondjoy]

Yes.. and I believe the title should have included "natural" birth.

[Fierce Allegiance]

Not exactly. This girl is the first test tube baby, who has now given birth. Her sister, not the first test tube baby, is the first test tube baby to have given birth.

[Tanniker Smith]

Misplaced modifiers.

Louise Brown was the first test tube baby. She gave birth.

Her sister, Natalie, was also a test-tube baby. She was first of the test-tube babies to give birth.

So Louise was the first test-tube baby and she gave birth.
And Natalie was the first of the test-tube babies to have given birth.

That concludes English class for today.

No int the case of Natalie, she was the test-tube baby who had a child first. In the case of Louise, she was the first test tube baby, and she just had a child.
