Why Is It Not Seen as Child Abuse to Bring a Sick Baby in the World?

i get very worried and mad whenever i hear about woman who undergo fertility treatments or have insemination when they know they have passed the phase where they could have had a healthy baby. i don’t know where this trend came from, all these celebrities that are almost 40 having baby’s and twins. meanwhile almost all these children are sick. most have heart problems, others have some mental disabilities, hormone problems, growth problems, but most have heart problems. and it’s not like we don’t know like 20 years ago. we know that even if u take hormones or have Ur own egg inseminated, the child will have problems. most of these babies stay months is the cofeuse, and a lot don’t make it. I can not understand why a mother would want a child so bad even when she knows ( cause most pp know ok what the chances are of difficulties or an unhealthy child) why would u choose to bring that child to life, does every mother not dream of a healthy baby, do u not want the best for ur child. and this is a situation where u urself choose to bring that fetus to life, its something u do urself. to me this is very selfish and it not about the child its not about wanting a child to love, it’s about u, it’s about u wanting to say hey i can still have a baby, or wanting a certain life style for ur own benefit when u let the change for this lifestyle pas u by. cause most of these woman are woman that choose a certain lifestyle that did not allow them to have a child. and know this past lifestyle will influence their child, meaning, alcohol, smoking, drugs, pills ect. so to me woman in this situation willingly bringing an unhealthy child to life, a child that will have problems as he/she grows and if she wants a child or her own someday. I see this as child abuse and i wonder why nobody else.
there are so many children in this world that need a home, if u really want a child so bad what does it matter if u gave birth to it or not, or is it that u just want to give birth?
I have seen sick children, i have seen children that now are my age and have problems because there mother took hormones when she was already 35+ and i know a six year old girl that has had 2 heart transplants, kidney problems, cant go to school cant play and has to be around an oxygen tank all the time, just because her parents decided to have her when they were 45 and 60. ( and no it did not happen naturally) every i look at this woman i feel disgusted. Am i
the only one? ofcourse there are healty woman that need some extra hormones or vitamins but that is not what i am talking about here i am talking about cases where it is already known that there will be complications.
pls dont change the subject i am not talking about pp that get complications during pregnancy i know there are so many things that can go wrong that we dont have power over, i am not talking about abortion here. i am talking about pp talking this riks before there is a fetus like X said paying so much money and no it not your decicions cause this is not your life this is an other person a life that is not yours that what i am talking pp do not realize that your child is not just ur child its another person with a life of its own. and i write about it because i see it everyday and have 2 deal with it.
