In other words Kate decided to use fertility drugs.
Not only did Kate decide to use fertility drugs, but she almost certainly went against her fertility doctor's advice and proceeded with insemination in spite of ultrasounds showing a huge number of follicles. Doctors routinely advise cancellation of cycles with that many follicles, unless it's an IVF cycle where all the eggs will be taken out, but only a small number will be transferred back in after fertilization -- that's clearly not what this was. She wanted to make sure she didn't have to spend a few extra bucks to do another cycle, with lower hormone doses, so she went ahead. And now she wants us to pay for raising the huge brood she got.
She was PRESSURED, you patriarchal oppressor. We as a society MADE her take those shots.
Sheesh. The insensitivity around here! ;)
Worse. Rather than adhere to most responsible protocols, she chose to have more than two embryos implanted at the same time. Tick, tick, tick - DING! Quadruplets on top of twins.
The only one responsible for her situation is her.
Of course, she consults the only other living moron permitted to procreate after Darwin gave explicit instructions that she NOT DO SO, nature having rendered her infertile. This genius implants more than SEVEN embryos in one cycle and has a litter. I wonder how many the quack, who should have his/her license to practice revoked, actually implanted. My guess is more than seven.
