If you cannot guarantee your prospective offspring(s) with the fact that they won't suffer, be afflicted with illness, sadness, existential dread and injuries then you shouldn't be having kids in the first place.
Philosopher David Benatar presents in his book “Better Never to Have Been” an asymmetry that exists between existence and non-existence. I can not outline his whole work on here; I recommend reading his book if you want to know the big picture.
Put simply, the asymmetry illustrates how not existing is preferable over existing in any case. When you exist, you experience positive things, which is good, and negative things, which is bad. When you do not exist, you do not experience negative things, which is good. You also do not experience positive things, which is not bad, though, as not experiencing good things is only perceived as suffering when it is deprivation. Besides what are you being deprived of when you never had existed in the first place?
Not to mention they didn't even consented on being born in the first place.
Thus, non-existence is preferable as you do not experience suffering and are also not able to miss the delights you miss out on. To put it in a rather humorous way as an analogy: Have you ever felt pity for the poor non-existent inhabitants of Ernst Thälmann Island, for they can not behold the beautiful Caribbean beaches? How about the non existent incel that would be snooping around esoteric height growing or face fixing forums in the hopes of finding a girlfriend?
The only reason people reproduce is because of tradition and also because it feels good to fŭck which is one reason people tout the reproduce is "muh human rightz" (willingly passing on their sħitty disability inducing genetics thus condemning their children to a life of misery), had they even put in a modicum amount of thought none would be able to rationalize such a stupid decision in the first place.
Had you not existed you wouldn't have to worry about your height, your looks or women finding you attractive to begin with.
Wow, Great Honorable Philosopher ZUCC420 appeared in my post to waste so much time on the harangue riddled with unlogical nonsenses(I think you better turn to learn science not philosophy. It seems philosophy can't fit with your intelligence.)
If you are already convinced 'not experiencing good things' is 'not bad', then why experiencing bad thing is bad? Do you know what 'negative proposition' is? I think as a negative propostion, the true conclusion is 'not experencing good things is not bad while experiencing bad things is not good' if you've developed a really explicit logical thinking?
Secondly, if you are really obsessed with such outlandish ideology, what is the reason that you can use your smartphone or computer to write down this kind of addresses? From the way I understand all you said they should've preferred to be non-existent, therefore phones or computers should've also been non-existent since the inventors should've also been non-existent, let alone languages, or even philosophy itself(the philosopher should've been non-existent also right?)
Finally, who told you I wanted children? I've repeated like for billions of times I don't want children. So your speech was totally absurd in the logic and comprehension from the beginning to the end.
You are not sophisticated either at all.
Who told you having children is just a tradition? I am not saying tradition is never the component of the motivations of having children but having children is also a crystal of romance, in order to challenge how true to the core yourself and your romantic partner are and how much smartly and flexibly you can circumvent or even surmount the barriers that God sets up in your two's life after establishing a relationship/getting married, etc.
You are definitely like only ranging from 15 to 17 y.o rn at least you still haven't finished middle school. Your view of this world is very juvenile and bizarre, even appearing to be a pure psychopath who is pathetic enough to be suffering from psychiatric disorders in such a young age right?
