First, she's already 34 and wouldn't want a child with Down syndrome. Second, her twin advised her not to have a baby yet because it's hard to bear and raise one.
I've read other articles regarding the matter. They have different reasons.
- Some just hate children.
- Some won't want to spend time attending PTA meetings, or reading children books, or thinking of ways to discipline their kids, instead of having fun with friends and being out till the wee hours in the morning just enjoying their selves.
- Some wouldn't want their slim/sexy bodies to turn fatty, ugly secondary to pregnancy.
- Some wouldn't want to children who would likely to have abnormal or cancer-prone genes...
Ethicist (i.e. Catholics) won't agree with these reasons. They would argue that the purpose of marriage is to reproduce. To go forth and multiply (=p )... be procreative creatures...
Anyway. I'd prefer relaying to you these scientific facts (from Williams, and Novak).
1. The following are at risk of carrying an aneuploid fetus (or fetus with genetic or congenital disorders)
- women who will be at least 35 years old at the delivery of their singleton pregnancy (among 35-year-old gravidas/pregnant women the risk or incidence of Down syndrome is 1 in 250 cases and rises rapidly with increasing maternal age)
- women aged at least 31 years at the delivery of their dizygotic twin (non-identical twins) gestation (there is greater risk of Down syndrome if there are two fetuses than if there is one)
- women who have previously carried a fetus with an autosomal trisomy or triple X (chance to have another baby with defect is 1:100)
- women or their partners who have chromosomal translocation
- women or their parners who are carriers of chromosomal inversions
- history of triploidy
- repetitive early pregnancy losses
- women or partner has aneuploidy
- major fetal structural defect identified by ultrasound
