For your children. -You are being selfless because you disregard your own happiness so your "future children" don't have to experience any pain whatsoever. (e. G. Hardships of life, Disease, Losing their parents to death, Getting older, Their own death, Dangers of the world, School/work/love pain, Stress/fears/sadness etc. )
-You don't risk the mother's or child's health/life during pregnancy/birth. (Even if unlikely it is possible. And if that happens mother, Child or spouse will be unhappier e. G. Because of wrongful guilt)
-You don't risk the child being born unhealthy/unhappy. (5 out of 100 babys are born unheathy despite perfectly healthy parents) I also thought that would never ever happen to my child. Please do not gamble with someone else's life!
