I had the same issue, SarasGirl. Kids on the bus can be cruel when your parents are a little older than theirs. It's not cruel to have a child if you're defined as "over the child-bearing age."
She's a well-renowned psychologist, right? Even though she has three other children maybe she wanted to focus on her career more? You would be surprised, but a LOT of women are doing that rather than going out and having kids at the age of 20. Would you call those people selfish too?
My parents are older than most and they are just as capable of caring for me financially, emotionally and physically. Even though they couldn't lift me up and swing me around, my childhood wasn't limited either, they're not selfish people, they wanted to have a child later than other people, they wanted to live their lives before they decided to have another child, I don't think that makes them cruel in any sense.
And it's not as if this woman woke up one morning and said "hey...I'm gonna get pregnant today..." She put a lot of thought into having another child. She seems well-abled to take care of this child as well. She's not poor, she's not dead, and if she were in any health troubles the doctor would have strongly advised against it, or they would have lost the baby.
I'm sorry but I find your "cruel to the child" and "selfish" reasoning to be a little ill-informed. Cruel to the child is having a baby at whatever age and not putting any thought into it just accepting it as it comes. Cruel to the child is having it where you are in such a desolate state that you have no possible way to take care of it.
And as for the "cruel to the child" if they happen to die? So what? Everyone will die eventually, that doesn't make them cruel if they happen to die while their child is very young, that can happen to anyone, young or old. They could have cancer or know that they will die at a pre-determined age, but they still want to have a child, does that make these people cruel? For wanting to have their own baby?
For your argument, what if an older couple adopts a child and then dies? Is that not cruel as well?
The child may not have had their parents for as long as the rest of the children out there, but who's to say that their childhood, their life and all of its fairness was robbed of them?
